Summary     : Email filter with virus scanner and spamassassin support
Description :
amavisd-new is a high-performance and reliable interface between mailer
(MTA) and one or more content checkers: virus scanners, and/or
Mail::SpamAssassin Perl module. It is written in Perl, assuring high
reliability, portability and maintainability. It talks to MTA via (E)SMTP
or LMTP, or by using helper programs. No timing gaps exist in the design
which could cause a mail loss.

iptables Regel

Damit der AMaViS (A MAil Virus Scanner) auch über den AMaViS - amavisd-milter erreichbar ist und nicht das Empfangen der IP-Paket vom Paketfilter iptables blockiert wird, muss nachfolgende Regel zum iptables-Regelwerk hinzugefügt werden.

Um die aktuellen iptables-Regeln erweitern zu können, sollten diese erst einmal aufgelistet werden, was mit nachfolgendem Befehl durchgeführt werden kann:

# iptables -L -nv --line-numbers
Chain INPUT (policy ACCEPT 0 packets, 0 bytes)
num   pkts bytes target     prot opt in     out     source               destination         
1        0     0 ACCEPT     all  --  *      *       0.0.0.0/0            0.0.0.0/0           state RELATED,ESTABLISHED 
2        0     0 ACCEPT     icmp --  *      *       0.0.0.0/0            0.0.0.0/0           
3        0     0 ACCEPT     all  --  lo     *       0.0.0.0/0            0.0.0.0/0           
4        0     0 ACCEPT     tcp  --  *      *       0.0.0.0/0            0.0.0.0/0           state NEW tcp dpt:22  
5        0     0 REJECT     all  --  *      *       0.0.0.0/0            0.0.0.0/0           reject-with icmp-host-prohibited 

Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
num   pkts bytes target     prot opt in     out     source               destination         
1        0     0 REJECT     all  --  *      *       0.0.0.0/0            0.0.0.0/0           reject-with icmp-host-prohibited 

Chain OUTPUT (policy ACCEPT 0 packets, 0 bytes)
num   pkts bytes target     prot opt in     out     source               destination

Nachfolgende Befehle, fügen folgende iptables-Regeln dem iptables-Regelwerk nach der Position 4 hinzu, ohne das der Paketfilter angehalten werden muss:

  • -A INPUT -p tcp --dport 10014 -j ACCEPT
  • -A INPUT -p tcp --dport 10024 -j ACCEPT
  • -A INPUT -p tcp --dport 10026 -j ACCEPT

und hier der Befehl:

# iptables -I INPUT 5 -p tcp --dport 10014 -j ACCEPT
# iptables -I INPUT 6 -p tcp --dport 10024 -j ACCEPT
# iptables -I INPUT 6 -p tcp --dport 10026 -j ACCEPT

Ein erneute Abfrage des iptables-Regelwerts, sollte dann nachfolgend dargestellte Ausgabe ergeben, was mit folgendem Befehl durchgeführt werden kann:

# iptables -L -nv --line-numbers
Chain INPUT (policy ACCEPT 0 packets, 0 bytes)
num   pkts bytes target     prot opt in     out     source               destination         
1        0     0 ACCEPT     all  --  *      *       0.0.0.0/0            0.0.0.0/0           state RELATED,ESTABLISHED 
2        0     0 ACCEPT     icmp --  *      *       0.0.0.0/0            0.0.0.0/0           
3        0     0 ACCEPT     all  --  lo     *       0.0.0.0/0            0.0.0.0/0           
4        0     0 ACCEPT     tcp  --  *      *       0.0.0.0/0            0.0.0.0/0           state NEW tcp dpt:22
5        0     0 ACCEPT     tcp  --  eth0   *       0.0.0.0/0            0.0.0.0/0           tcp dpt:10014 state NEW
6        0     0 ACCEPT     tcp  --  eth0   *       0.0.0.0/0            0.0.0.0/0           tcp dpt:10024 state NEW
7        0     0 ACCEPT     tcp  --  eth0   *       0.0.0.0/0            0.0.0.0/0           tcp dpt:10026 state NEW
8        0     0 REJECT     all  --  *      *       0.0.0.0/0            0.0.0.0/0           reject-with icmp-host-prohibited 

Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
num   pkts bytes target     prot opt in     out     source               destination         
1        0     0 REJECT     all  --  *      *       0.0.0.0/0            0.0.0.0/0           reject-with icmp-host-prohibited 

Chain OUTPUT (policy ACCEPT 0 packets, 0 bytes)
num   pkts bytes target     prot opt in     out     source               destination

Die neuen Zeilen sind an Position 5 (INPUT) und Position 7 (INPUT) zu sehen, hier nachfolgend zur Verdeutlichung noch einmal dargestellt (nur relevanter Ausschnitt):

...
5        0     0 ACCEPT     tcp  --  eth0   *       0.0.0.0/0            0.0.0.0/0           tcp dpt:10014 state NEW
6        0     0 ACCEPT     tcp  --  eth0   *       0.0.0.0/0            0.0.0.0/0           tcp dpt:10024 state NEW
7        0     0 ACCEPT     tcp  --  eth0   *       0.0.0.0/0            0.0.0.0/0           tcp dpt:10026 state NEW
...

Um diese iptables-Regel dauerhaft, auch nach einem Neustart des Server, weiterhin im iptables-Regelwerk zu speichern, muss nachfolgend dargestellter Befehl abschließend noch ausgeführt werden:

# /usr/sbin/iptables-save > /etc/sysconfig/iptables 

Konfiguration: amavisd

Bevor mit der eigentlichen Konfiguration begonnen werden soll, kann mit nachfolgenden Befehl ein Start des AMaViS im Vordergrund und im DEBUG-Modus durchgeführt werden, um überprüfen zu können, ob die gewünschten Module geladen werden und ob für das entpacken der von Archiven die benötigten Programme zur Verfügung stehen.

Ein Start im des AMaViS im Vordergrund und im DEBUG-Modusm kann mit nachfolgendem Befehl durchgeführt werden:

# amavisd -u amavis -c /etc/amavisd/amavisd.conf debug

/etc/amavisd/amavisd.conf

Standardmäßig wird nach der Installation von AMaViS in nachfolgendem Verzeichnis mit nachfolgendem Namen die Konfigurationsdatei für den AMaViS hinterlegt:

  • /etc/amavisd/amavisd.conf

Um alle möglichen Konfigurationsparameter einsehen zu können, wird mit der Installation des AMaViS nachfolgende Default-Konfigurationsdatei in nachfolgendem Verzeichnis mit nachfolgendem Namen installiert, welche als Referenz für alle Konfigurationsdirektiven verwendet werden kann:

  • /usr/share/doc/amavisd-new-2.10.1/amavisd.conf-default bzw.
  • /usr/share/doc/amavisd-new-2.11.0/amavisd.conf-default

Welche Konfigurationsparameter gesetzt werden sollten, soll in nachfolgender Beispielkonfigurationsdatei dargestellt werden.

use strict;
 
## AMaViS - amavsid-new configuration.
 
## The 'after-default' comment indicates that these variables obtain their
## default value if the config file left them undefined. It means these values
## are not yet available during processing of the configuration file, but that
## they can derive their value from other configurations variables no matter
## where in the configuration file they appear.

Dienst/Daemon-Start einrichten: amavisd

Um einen AMaViS, welcher als Dienst/Daemon als Hintergrundprozess läuft, auch nach einem Neustart des Servers zur Verfügung zu haben, soll der Dienst/Daemon mit dem Server mit gestartet werden, was mit nachfolgendem Befehl realisiert werden kann:

# systemctl enable amavisd.service
ln -s '/usr/lib/systemd/system/amavisd.service' '/etc/systemd/system/multi-user.target.wants/amavisd.service'

Eine Überprüfung, ob beim Neustart des Server der 'amavisd-Dienst/Daemon wirklich mit gestartet wird, kann mit nachfolgendem Befehl erfolgen und sollte eine Anzeige, wie ebenfalls nachfolgend dargestellt ausgeben:

# systemctl list-unit-files --type=service | grep -e amavisd.service
amavisd.service                        enabled
bzw.
# systemctl is-enabled amavisd.service
enabled

Erster Start: amavisd

Um den AMaViS zu starten, kann nachfolgender Befehl angewandt werden:

# systemctl start amavisd

Eine Überprüfung ob der Start des AMaViS erfolgreich war, kann mit nachfolgendem Befehl durchgeführt werden, welcher eine Ausgabe in etwa wie nachfolgende erzeugen sollte:

# systemctl status amavisd

Konfiguration: amavisd-milter

/etc/amavisd/amavisd-milter.conf

Standardmäßig wird nach der Installation von AMaViS - amavsid-milter in nachfolgendem Verzeichnis mit nachfolgendem Namen die Konfigurationsdatei für den AMaViS - amavisd-milter hinterlegt:

  • /etc/amavisd/amavisd-milter.conf

Nachfolgende Änderungen sind an der Konfigurationsdatei /etc/amavisd/amavisd-milter.conf durchzuführen:

(Komplette Konfigurationsdatei)

#         User to run under (must be same as amavisd daemon)
AMAVIS_USER=amavis
 
#         Set working directory (default /var/amavis).

#         Communication socket between sendmail and amavisd-milter (default
#         /var/amavis/amavisd-milter.sock).  The protocol spoken over this
#         socket is MILTER (Mail FILTER).  It must agree with the
#         INPUT_MAIL_FILTER entry in sendmail.mc
#         The socket should be in "proto:address" format:
#         o   {unix|local}:/path/to/file - A named pipe.
#         o   inet:port@{hostname|ip-address} - An IPV4 socket.
#         o   inet6:port@{hostname|ip-address} - An IPV6 socket.

#         Use this pid file (default /var/amavis/amavisd-milter.pid).
#         Better to create /var/run/amavis and put it there
#PID_FILE=/var/run/amavisd/amavisd-milter.pid
 
#         Maximum concurrent amavisd connections (default 0 - unlimited
#         number of connections).  It must agree with the $max_servers
#         entry in amavisd.conf.
# Tachtler
# default: MAX_CONNECTIONS=2
MAX_CONNECTIONS=4
 
#         Maximum wait for connection to amavisd in seconds (default 300 =
#         5 minutes).  It must be less then sending MTA timeout for a
#         response to the final "."  that terminates a message on sending
#         MTA.  sendmail has default value 1 hour, postfix 10 minutes and
#         qmail 20 minutes.  We suggest to use less than 10 minutes.
MAX_WAIT=300
 
#         sendmail connection timeout in seconds (default 600 = 10 min-
#         utes).  It must agree with the INPUT_MAIL_FILTER entry in send-
#         mail.mc and must be greater than or equal to the amavisd-new con-
#         nection timeout.  When you use other milters (especially time-
#         consuming), the timeout must be sufficient to process message in
#         all milters.
MAILDAEMON_TIMEOUT=600
 
#         amavisd-new connection timeout in seconds (default 600 = 10 min-
#         utes).  This timeout must be sufficient for message processing in
#         amavisd-new.  It's usually a good idea to adjust them to the same
#         value as sendmail connection timeout.
AMAVISD_TIMEOUT=600

Nachfolgende Änderungen sollten vorgenommen werden:

  • SOCKET=inet:10014@192.168.0.70

Socket über den mit dem AMaViS - amavisd-milter über die IP-Adresse: 192.168.0.70 und den Port: 10014 kommuniziert werden kann.

  • AMAVISD_SOCKET=/var/run/amavisd/amavisd.sock

Socket über den der AMaViS - amavisd-milter mit dem AMaViS kommunizieren kann.

  • MAX_CONNECTIONS=4

Anzahl der maximalen gleichzeitigen Verbindungen zwischen Postfix und AMaViS - amavisd-milter.

:!: WICHTIG - Dies muss mit der Angabe in der AMaViS Konfigurationsdatei

  • /etc/amavisd/amavisd.conf

und dem Parameter

  • $max_servers = 4

übereinstimmen!

Dienst/Daemon-Start einrichten: amavisd-milter

Um einen AMaViS - amavisd-milter, welcher als Dienst/Daemon als Hintergrundprozess läuft, auch nach einem Neustart des Servers zur Verfügung zu haben, soll der Dienst/Daemon mit dem Server mit gestartet werden, was mit nachfolgendem Befehl realisiert werden kann:

# systemctl enable amavisd-milter.service
ln -s '/usr/lib/systemd/system/amavisd-milter.service' '/etc/systemd/system/multi-user.target.wants/amavisd-milter.service'

Eine Überprüfung, ob beim Neustart des Server der 'amavisd-milter-Dienst/Daemon wirklich mit gestartet wird, kann mit nachfolgendem Befehl erfolgen und sollte eine Anzeige, wie ebenfalls nachfolgend dargestellt ausgeben:

# systemctl list-unit-files --type=service | grep -e amavisd-milter.service
amavisd-milter.service                 enabled
bzw.
# systemctl is-enabled amavisd-milter.service
enabled

Erster Start: amavisd-milter

Um den AMaViS - amavisd-milter zur Kommunikation mit dem AMaViS zu starten, kann nachfolgender Befehl angewandt werden:

# systemctl start amavisd-milter

Eine Überprüfung ob der Start des AMaViS - amavisd-milter erfolgreich war, kann mit nachfolgendem Befehl durchgeführt werden, welcher eine Ausgabe in etwa wie nachfolgende erzeugen sollte:

# systemctl status amavisd-milter

Konfiguration: RAM-Disk

Eine sehr gute Möglichkeit die Performance für AMaViS zu steigern, ist eine RAM-Disk anzulegen. Dabei sollte natürlich auf die Hardware des Servers geachtete werden, aber auch auf die Gegebenheiten von AMaViS.

Um die benötigte Größe einer RAM-Disk berechnen zu können, was jedoch eher eine theoretische Größe ist, kann folgende Formel herangezogen werden:

max. AMaViS-Instanzen * (max. e-Mailgröße + (max. e-Mailgröße * Auspackfaktor))

Hier ein Beispiel:

Für 20 AMaViS-Instanzen bei einer max. e-Mailgröße von 30 MB und einem Auspackfaktor von 1,5 ergibt das eine RAM-Disk mit der Größe von 1,5 GB!

:!: Dies ist aber wie schon erwähnt, nur ein theoretischer Wert, da nicht jede e-Mail die max. Größe hat und es auch vom Netzwerkverkehr - sprich der Physik der Netzwerkkarte - nicht möglich sein dürfte, so viel Daten in kürzester Zeit (bis AMaViS-Instanzen wieder zur Verfügung stehen) zu transferieren!

Für einen kleinen privaten e-Mail-Server wird sicherlich auch eine kleinere Größe an RAM-Disk völlig ausreichend sein!

Deshalb kann mit folgenden Größen für einen kleinen privaten e-Mail-Server durchaus gerechnet werden:

Für 4 AMaViS-Instanzen bei einer max. e-Mailgröße von 10 MB und einem Auspackfaktor von 1,5 ergibt das eine RAM-Disk mit der Größe von 100 MB!

/etc/fstab

Unter CentOS Version 7.x kann mit folgendem Eintrag in der /etc/fstab kann eine RAM-Disk in der Größe von 96 MB angelegt werden (nur relevanter Ausschnitt):

...
tmpfs /var/spool/amavisd/tmp		tmpfs defaults,size=96m,mode=755,uid=399,gid=399	0 0

Zum Mounten nach dem Eintrag in der /etc/fstab kann folgender Befehl ausgeführt werden:

# mount /var/spool/amavisd/tmp

:!: WICHTIG - Falls gewünscht kann die soeben angelegte RAM-Disk auch für andere Programme lesbar gemacht werden, z.B. für Überwachungs- und Auswertungs-Tools. Dafür sollte folgender Befehl für die entsprechenden Zugriffsrechte auf das Verzeichnis /var/spool/amavisd/tmp und dessen übergeordnetem Verzeichnis /var/spool/amavisd sorgen:

# chmod 755 /var/spool/amavisd

Zur Überprüfung, ob die Verarbeitung wirklich schneller von statten geht, hier zwei Auszüge aus der LOG-Datei /var/log/maillog, der gleichen e-Mail, einmal ohne und anschließend mit RAM-Disk:

...

Konfiguration: DKIM

DKIM - DomainKeys ist ein Identifikationsprotokoll zur Sicherstellung der Authentizität von E-Mail-Absendern, das von Yahoo entwickelt wurde und seit Ende 2004 in Erprobung ist. Es wurde konzipiert, um bei der Eindämmung von unerwünschter E-Mail wie Spam oder Phishing zu helfen.

Genauere und Detailliertere Informationen können unter folgendem Link nachgelesen werden - DomainKeys. Wie auch in anderen Bereichen, wenn es um Verschlüsselung und Signierung geht z.B. (ssh, gnupg, s_mime) ist es auch logischerweise beim Einsatz von DKIM erforderlich, ein Schlüsselpaar, bestehend aus einem

  • öffentlichen Schlüssel
  • privaten Schlüssel

zu erstellen.

Vor der eigentlichen Erstellung des Schlüsselpaares, ist es jedoch zwingend erforderlich ein Verzeichnis und ein Unterverzeichnis zu erstellen, in dem AMaViS später den privaten Schlüssel finden kann. Dies könnte z.B. im Verzeichnis

  • /etc/pki/

mit nachfolgenden Befehlen durchgeführt werden:

Erstellung eines Verzeichnisses und Unterverzeichnisses /etc/pki/amavis/dkim

# mkdir -p /etc/pki/amavis/dkim

Schlüssel erstellen

Mit nachfolgendem Befehl wird das Schlüsselpaar jetzt

  • im Verzeichnis /etc/pki/amavis/dkim
  • als dkim.key-Datei im PEM-Dateiformat

erstellt:

# amavisd genrsa /etc/pki/amavis/dkim/dkim.key
Private RSA key successfully written to file "/etc/pki/amavis/dkim/dkim.key" (1024 bits, PEM format)
bzw. mit einer höheren bit Anzahl:
# amavisd genrsa /etc/pki/amavis/dkim/dkim.key 4096
Private RSA key successfully written to file "/etc/pki/amavis/dkim/dkim.key" (4096 bits, PEM format)

:!: WICHTIG - Damit AMaViS auf die private Schlüssel-Datei auch Zugriff hat, ist es erforderlich die Besitz- und Dateirechte wie folgt mit nachfolgenden Befehlen anzupassen:

# chown amavis.amavis /etc/pki/amavis/dkim/dkim.key
# chmod 600 /etc/pki/amavis/dkim/dkim.key

Die Verzeichnisstruktur und deren Inhalt sollte danach in etwa wie folgt aussehen und kann mit nachfolgenden Befehlen angezeigt werden (nur relevanter Ausschnitt):

# ll /etc/pki/
total 44
drwxr-xr-x 3 root root 4096 Jul 17 10:29 amavis
...

# ll /etc/pki/amavis/

drwxr-xr-x 2 root root 4096 Jul 17 10:41 dkim

# ll /etc/pki/amavis/*
total 4
-rw------- 1 amavis amavis 887 Jul 17 10:41 dkim.key

Der Inhalt der privaten Schlüssel-Datei kann mit nachfolgendem Befehl angezeigt werden und sollte in etwa wie folgt aussehen:

# cat /etc/pki/amavis/dkim/dkim.key

in AMaViS eingebunden werden.

DNS-Eintrag

:!: WICHTIG - Um selbst e-Mails signieren zu können, ist es erforderlich, dass der öffentliche Schlüssel via DNS abfragbar ist, was durchaus die Mithilfe des Providers erfordern kann!

Dazu ist es erforderlich erst einmal den öffentlichen Schlüssel mit der Hilfe von AMaViS aus der Schlüsseldatei /etc/pki/amavis/dkim/dkim.pem zu erhalten, was mit nachfolgendem Befehl erreicht werden kann:

# amavisd -c /etc/amavisd/amavisd.conf showkeys tachtler.net
; key#1 1024 bits, i=main, d=tachtler.net, /etc/pki/amavis/dkim/dkim.key
main._domainkey.tachtler.net.	3600 TXT (
  "v=DKIM1; h=sha256; p="
  "MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCW697RxGpSmHUxXFMgirRcDKJR"
  "RxoDuuIxlH/69QsHeee+hBC0Uwg72tcQ8dkmQfJwpcHAIt8nP/0VQnRc2uyRr+ln"

  "iJw8V1oSoafME1WklQIDAQAB")

Welcher aber in nachfolgender Form in den DNS-Record eingetragen werden muss (ohne „-Zeichen und <leer>-Zeichen):

v=DKIM1; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCW697RxGpSmHUxXFMgirRcDKJRRxoDuuIxlH/69QsHeee+hBC0Uwg72tcQ8dkmQfJwpcHAIt8nP/0VQnRc2uyRr+lnSp89Diahd3frfgnPnyKjhoNglJNlsinEksKnsQ40G6rki1kH3Sf0mq+Hn0RYozkYiJw8V1oSoafME1WklQIDAQAB

Nachfolgende DNS-Einträge müssen zum DNS hinzugefügt werden, um den öffentlichen Schlüssel via DNS abfragbar zu machen (nur relevanter Ausschnitt):

...
main._domainkey.tachtler.net.           IN      TXT     "v=DKIM1; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCW697RxGpSmHUxXFMgirRcDKJRRxoDuuIxlH/69QsHeee+hBC0Uwg72tcQ8dkmQfJwpcHAIt8nP/0VQnRc2uyRr+lnSp89Diahd3frfgnPnyKjhoNglJNlsinEksKnsQ40G6rki1kH3Sf0mq+Hn0RYozkYiJw8V1oSoafME1WklQIDAQAB"
...

:!: HINWEIS - Es ist nicht erforderlich, dass die neue Sub-Domain - main._domainkey.tachtler.net auf eine gültige IP-Adresse auflöst, noch irgendwelche MX-Einträge besitzt!

:!: WICHTIG - Nach dieser Änderung am DNS, ist ein Neustart des jeweiligen DNS-Servers notwendig!

Zum testen, ob AMaViS den öffentlichen Schlüssel richtig erreichen und abfragen kann, sind z.B. nachfolgende Befehle hilfreich:

AMaViS-Test

# amavisd -c /etc/amavisd/amavisd.conf testkeys tachtler.net
TESTING#1 tachtler.net: main._domainkey.tachtler.net => pass

DNS-Abfrage (beim eigenen DNS-Server)

DKIM aktivieren

Jetzt ist der Zeitpunkt für die Aktivierung von DKIM mit AMaViS gekommen.

Nachdem nun die DNS-Einträge verfügbar sind, kann abschließend das Signieren von e-Mails aktiviert werden, in dem in der Konfigurationsdatei

  • /etc/amavisd/amavisd.conf

nachfolgende Konfiguration durchgeführt wird:

(Nur relevanter Ausschnitt):

...
## DKIM SIGNING
 
# Signieren der ausgehenden e-Mails mit dem Schluessel unter dkim_key.
$enable_dkim_signing = 1;
...

Received-Zeilen ausnehmen

Laut RFC 4871 können auch die

  • Received: from-Zeilen

zur Signierung der e-Mail mit herangezogen werden.

Dies hat jedoch den Nachteil, dass bei einer Veränderung der Received: from-Zeilen im Nachhinein, wie es z.B. bei der Einlieferung durch Postfix via smtpd_proxy_filter (Pre-Queue) bei AMaViS der Fall sein könnte, die DKIM-Sigantur sprichwörtlich „kaputt“ geht. Siehe nachfolgenden Auszug aus den Header-Zeilen (nur relevanter Ausschnitt):

...
Authentication-Results: viruswall.idmz.tachtler.net (amavisd-new);
	dkim=fail (1024-bit key) reason="fail (message has been altered)"
	header.d=tachtler.net
...

Dies kann durch hinzufügen von nachfolgender Konfigurationszeile in die

  • /etc/amavisd.conf

$signed_header_fields{'received'} = 0;  # turn off signing of Received
verhindert werden, indem die Received: from-Zeilen nicht mehr mit in die Berechnung der DKIM-Signatur mit einfließen.

DKIM-Test: AMaViS

Mit nachfolgendem Befehl, kann eine Test des Gültigkeit der DKIM-Signatur unter Zuhilfenahme von AMaViS durchgeführt werden:

# amavisd testkeys
TESTING#1: main._domainkey.tachtler.net      => pass

DKIM-Test: DNS

Mit nachfolgenden Befehlen, kann eine entsprechende DNS-Abfrage durchgeführt werden, um zu testen, ob der entsprechende Schlüssel im DNS korrekt eingebunden ist:

# host -t TXT main._domainkey.tachtler.net
main._domainkey.tachtler.net descriptive text "v=DKIM1\; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCW697RxGpSmHUxXFMgirRcDKJRRxoDuuIxlH/69QsHeee+hBC0Uwg72tcQ8dkmQfJwpcHAIt8nP/0VQnRc2uyRr+lnSp89Diahd3frfgnPnyKjhoNglJNlsinEksKnsQ40G6rki1kH3Sf0mq+Hn0RYozkYiJw8V1oSoafME1WklQIDAQAB"

DKIM-Test: e-Mail

Folgender Text-Auszug sollte nun beim e-Mail-Verkehr im Quelltext im Header einer e-Mail erscheinen (nur relevanter Ausschnitt):

...
DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/simple; d=tachtler.net; h=
	user-agent:content-transfer-encoding:content-disposition

	KenY0BIV4rLgWIjqkdCFeW40IgxNj3ur5WNxHPxJWGdpLGtP+SPJYBRM/EM=
...

Der empfangende Mailserver ist mit Hilfe des Authentication-Results:-Header in der Lage festzustellen, ob die eMail unverändert angekommen und somit nicht manipuliert wurde:

Authentication-Results: viruswall.dmz.tachtler.net (amavisd-new);
	dkim=pass (1024-bit key) header.d=tachtler.net

Wurde die Nachricht hingegen verändert, so schlägt die Überprüfung fehl:

Authentication-Results: viruswall.dmz.tachtler.net (amavisd-new);
	dkim=fail (1024-bit key) reason="fail (message has been altered)"
	header.d=tachtler.net

Konfiguration: alterMIME

:!: WICHTIG - Beim Einsatz von amavisd-milter zur Verbindung zwischen Postfix und AMaViS kann alterMIME innerhalb von AMaViS nicht eingesetzt werden !!! :!:

Die OpenSource-Variante von alterMIME kann zu folgenden Aktionen in Bezug auf e-Mail's genutzt werden:

  • Einfügen von sog. „Disclaimern“ - e-Mail Fußzeilen bei ein- und ausgehenden e-Mails
  • Einfügen von frei wählbaren „X-Header“-Angaben im e-Mail-Header
  • Verändern eines oder mehreren bereits in e-Mail-Header vorhandenen „X-Header“
  • Entfernen von Dateianhängen basierend auf Dateinamen, oder Dateihalten
  • Austausch von Dateianhängen basierend auf Dateinamen

Bevor mit der eigentlichen Konfiguration zur Integration von alterMIME in AMaViS begonnen werden soll, ist es empfehlenswert, um die Übersicht nicht zu verlieren, folgendes Verzeichnis mit nachfolgendem Befehl anzulegen:

# mkdir /etc/amavisd/altermime

:!: WICHTIG - Da benutzereigene „Disclaimer“ verwenden werden sollen, muss für jede e-Mail-Adresse in der Konfigurationsdatei /etc/amavisd/amavisd.conf - jeweils auch eine „Disclaimer-Datei“ für PLAIN-Text und HTML-Code nach z.B. folgendem Schema angelegt werden:

  • disclaimer_<Benutzername>.text
  • disclaimer_<Benutzername>.html

Die Dateien können mit folgenden Befehlen angelegt werden:

# touch /etc/amavisd/altermime/disclaimer_postmaster.text
# touch /etc/amavisd/altermime/disclaimer_postmaster.html
und

:!: Abschließend muss noch der Inhalt der jeweiligen benutzereigenen „Disclaimer“-Datei entsprechend angepasst werden. Hier ein Beispiel für

  • /etc/amavsid/altermime/disclaimer_postmaster.text

---------------------
Disclaimer postmaster
---------------------

/etc/amavisd/amavisd.conf

Um alterMIME in AMaViS zu integrieren, sind nachfolgende Konfigurationseinstellungen in der AMaViS-Konfigurationsdatei /etc/amavisd/amavisd.conf notwendig.

Die relevanten Änderungen gegenüber der Standard-Konfiguration sollen durch nachfolgende Anpassungen vorhandener Einstellungen in /etc/amavsid/amavisd.conf durchgeführt werden:

(Nur relevanter Ausschnitt):

...
# Tachtler
$altermime = '/usr/bin/altermime';     # a path to the program
@altermime_args_defang     = qw(--verbose --removeall);
@altermime_args_disclaimer = qw(--disclaimer=/etc/amavsid/altermime/_OPTION_.text --disclaimer-html=/etc/amavisd/altermime/_OPTION_.html);
@disclaimer_options_bysender_maps = (
      { 'postmaster@tachtler.net' => 'disclaimer-postmaster',
      { 'abuse@tachtler.net'      => 'disclaimer-abuse',
        '.'                       => 'disclaimer-default' },
    );
$defang_maps_by_ccat{+CC_CATCHALL} = [ 'disclaimer' ];
...
...
...
@mynetworks = qw( 0.0.0.0/32 127.0.0.0/8 [::1] 192.168.0.0/24 192.168.1.0/24 192.168.2.0/2488.217.171.167/32 );
...

:!: WICHTIG - Falls e-Mails durch einen lokalen kleinen MUA Mail User Agent wie z.B. mutt direkt in ein Postfach einfach auf die Festplatte geschrieben werden, ist es erforderlich auch die IP-Adresse - 0.0.0.0/32 in die Liste von

  • @mynetworks = qw( 0.0.0.0/32 127.0.0.0/8 [::1] 192.168.0.0/24 192.168.1.0/24 192.168.2.0/2488.217.171.167/32 );

mit aufzunehmen!

:!: WICHTIG ist auch, das Einfügen folgender Zeile

  • allow_disclaimers => 1,  # enables disclaimer insertion if available

in den policy_banks: MYNETS bzw. ORGINATING, da sonst der „Disclaimer“ nicht eingefügt wird!

Konfiguration: TLS

:!: WICHTIG - Nachfolgende Punkte sind bei der TLS Transport Verschlüsselung zu beachten:

  1. Zu AMaViS kann TLS nur bei content_filter genutzt werden
  2. Zu AMaViS kann TLS NICHT mit smtpd_proxy_filter genutzt werden
  3. Von AMaViS kann TLS nur bei Anforderung durch z.B. Postfix genutzt werden

Um auch beim AMaViS TLS Transport Verschlüsselung einsetzen zu können, ist es aktuell erforderlich einen patch einzusetzen, da sonst nachfolgende Warnmeldung in der LOG-Datei /var/log/maillog bei der Aktivierung der TLS Transport Verschlüsselung zu sehen ist:

_WARN: *******************************************************************\n Using the default of 
SSL_verify_mode of SSL_VERIFY_NONE for client\n is deprecated! Please set SSL_verify_mode to SSL_VERIFY_PEER\n 
together with SSL_ca_file|SSL_ca_path for verification.\n If you really don't want to verify the certificate 
and keep the\n connection open to Man-In-The-Middle attacks please set\n SSL_verify_mode explicitly to 
SSL_VERIFY_NONE in your application.\n*******************************************************************\n  
at /usr/sbin/amavisd line 8392.

:!: WICHTIG - Ab der Version 2.11.x von AMaViS, ist ein Patch nicht mehr notwendig!!!

Nachfolgender patch basierend auf einem patch von Markus Benning mit einigen Ergänzungen von Klaus Tachtler, welcher in den AMaViS integriert werden muss, damit

  • nachfolgende Optionen
    • SSL_cipher_list
    • SSL_version
    • SSL_CAfile
    • SSL_honor_cipher_order
    • und von Klaus Tachtler - SSL_verify_mode

bestimmt werden können.

:!: HINWEIS - Die Definition von SSL_verify_mode behebt übrigens die Warnmeldung!

Bis AMaViSd-new 2.10.x - TLS-patch

:!: WICHTIG - Ab der Version 2.11.x von AMaViS, ist ein Patch nicht mehr notwendig!!!

Nachfolgender patch muss in den AMaViS integriert werden, damit TLS Transport Verschlüsselung entsprechend genutzt werden kann:
