Spamassassin für AMaViS unter CentOS 7.x

Bild: Logo Apache Spamassassin

SpamAssassin ist ein weitverbreitetes Filterprogramm, mit dem unerwünschte eMails (Spam) automatisch erkannt und aussortiert werden können. Ebenso wie AMaViS ist SpamAssassin ein Perl-Programm, mit der eine inhaltliche Bewertung einer eMail erfolgt. SpamAssassin selbst ermittelt und berechnet einen Scoring-Wert einer jeden eMail und übergibt diesen Wert an AMaVis. AMaViS selbst kann nun an Hand des übermittelten Scoringwertes eine eMail durchlassen, taggen (also z.B. die Betreffzeile manipulieren) oder ablehnen. SpamAssassin ist also nur ein Backendsystem von AMaViS.

Für die Unterscheidung zwischen HAM1) und SPAM2) bedient sich SpamAssassin unterschiedlicher Techniken:

  • Abfrage von RBLs3).
  • Abfrage von Prüfsummenbasierten Filtern wie DCC, Pyzor und Razor.
  • Nutzung regulärer Ausdrücke zum statischen Bewerten der eMails
  • Nutzung interner Bayesscher Filter, die auf Grund der Einteilung der bisher empfangenen eMails statistisch die Wahrscheinlichkeit von HAM zu SPAM ermitteln.

Wie üblich installieren wir die benötigten Programmpakete via YUM, falls das Paket nicht gleich bei der Installation von AMaViS mitinstalliert wurde.

 # yum install spamassassin -y

Was uns das Paket alle bei der Installation mitgebracht hat, zeigt uns ein Blick in das installierte rpm.

 # rpm -qil spamassassin

To enable spamassassin, if you are receiving mail locally, simply add
this line to your ~/.procmailrc:                                     
INCLUDERC=/etc/mail/spamassassin/spamassassin-default.rc             

To filter spam for all users, add that line to /etc/procmailrc
(creating if necessary).

spamassassin

Eine besondere Konfiguration von SpamAssassin ist eigentlich nicht notwendig. Im Verzeichnis /etc/mail/spamassassin/ befindet sich die Konfigurationsdatei local.cf mit Hilfe derer lokale Anpassungen an der Installation vorgenommen werden können.

 # vim /etc/mail/spamassassin/local.cf
/etc/mail/spamassassin/local.cf
 These values can be overridden by editing ~/.spamassassin/user_prefs.cf
# (see spamassassin(1) for details)
 
# These should be safe assumptions and allow for simple visual sifting
# without risking lost emails.
 
# Ab welchem Punktestand soll eine eMail als Spam betrachtet werden?
required_hits 5
 
# Diese Option legt fest, wie SpamAssassin eine als Spam eingestufte E-Mail markieren soll. Sofern 
# report_safe 0 definiert wurde, fügt Spamassassin lediglich einige X-Spam-Header ein und lässt die
# E-Mail ansonsten unverändert.
report_safe 0
 
# Mit dieser Option wird definiert, daß eine Nachricht, welche als SPAM klassifiziert wurde, zusätzlich 
# mit dem Hinweis "[SPAM]" in der Betreffzeile gekennzeichnet werden sollen.
rewrite_header Subject [SPAM]
 
# Diese Direktive bestimmt, welche Sperrmethode verwendet wird, um die beiden Datenbanken (Bayes- und 
# Autowhitelisting) vor gleichzeitigen Zugriffen zu schützen. Wenn sichergestellt ist, daß auf die beiden 
# Datenbanken nie über ein NFS zugegriffen wird, kann auf Unix-Plattformen  erheblich an Performance 
# gewonnen werden, indem die Sperrmethode flock verwendet wird.

Somit müssen wir auf Seiten von AMaViS keine zusätzlichen Einstellungen vornehmen.

erster Systemstart

Nun können wir unseren Anti-SMAP-Daemon das erste mal starten.

 # systemctl start spamassassin

Den Status des Daemon fragen wir bei Bedarf wie folgt ab.

 # systemctl status spamassassin

Im Maillog wird der Start des Daemon entsprechend protokolliert.

In der Prozessübersicht finden wir dazu dann auch entsprechend folgene Prozesse.

 # ps auxwww | grep spam
root     12350  0.3  3.3 283472 64072 ?        Ss   18:52   0:02 /usr/bin/spamd --pidfile /var/run/spamd.pid -d -c -m5 -H

root     12352  0.0  3.2 283472 61152 ?        S    18:52   0:00 spamd child

Mit folgendem Befehl kann überprüft werden, auf welchem Port unser SpamAssassin horcht:

 # lsof -i :783
COMMAND     PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
/usr/bin/ 12350 root    5u  IPv4 122819      0t0  TCP localhost:783 (LISTEN)
spamd     12351 root    5u  IPv4 122819      0t0  TCP localhost:783 (LISTEN)
spamd     12352 root    5u  IPv4 122819      0t0  TCP localhost:783 (LISTEN)

Das gleiche können wir natürlich auch via netstat abrufen.

 # netstat -tulpen | grep spamd
 tcp        0      0 127.0.0.1:783           0.0.0.0:*               LISTEN      0          122819     12350/spamd.pid -d

automatisches Starten des Dienste beim Systemstart

Damit nun unser AMaViS-Server beim Booten automatisch gestartet wird, nehmen wir noch folgende Konfigurationsschritte vor.

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

Wollen wir überprüfen ob der Dienst automatisch startet, verwenden wir folgenden Aufruf.

 # systemctl is-enabled spamassassin
 enabled

Die Rückmeldung enabled zeigt an, dass der Dienst automatisch startet; ein disabled zeigt entsprechend an, dass der Dienst nicht automatisch startet.

Haben wir die Konfiguration unseres AMaViS fertiggestellt, können wir uns auch daransetzen unsere Spamassassin-Installation zu überprüfen.

HAM

Haben wir unsere AMaViS-Konfiguration abgeschlossen, schicken wir uns entweder via telnet eine Nachricht, oder nutzen das Hilfsprogramm swaks für den tippfaulen Admin.

This is the GTUBE, the

        Test for
        Unsolicited
        Bulk
        Email

If your spam filter supports it, the GTUBE provides a test by which you
can verify that the filter is installed correctly and is detecting incoming
spam. You can send yourself a test mail containing the following string of
characters (in upper case and with no white spaces and line breaks):

XJS*C4JDBQADN1.NSBN3*2IDNEN*GTUBE-STANDARD-ANTI-UBE-TEST-EMAIL*C.34X

You should send this test mail from an account outside of your network.
