Postfix
ISH Konfiguration
Siehe mein Posting bei Fedoraforum.de.
Mit TLS und CRAM-MD5
relayhost = smtp.ish.de smtp_sasl_auth_enable = yes smtp_use_tls = yes smtp_sasl_security_options = noanonymous smtp_sasl_mechanism_filter = cram-md5
Ohne TLS , PLAIN/LOGIN
relayhost = smtp.ish.de smtp_sasl_auth_enable = yes smtp_use_tls = no smtp_sasl_security_options = noanonymous smtp_sasl_mechanism_filter = plain,login,cram-md5
SpamAssassin Integration
Siehe Anleitung hier.
Meine Schritte:
- Spamassassins von openSUSE verwenden
- User und Gruppe filter angelegt mit $HOME=/home/filter
- Datei /home/filter/sc/filter.sh angelegt mit 755 Permissions und filter:filter Owner. Dateininhalt:
#!/bin/sh
INSPECT_DIR=/var/spool/filter
SENDMAIL=/usr/sbin/sendmail
SPAMASSASSIN=/usr/bin/spamc
# Exit codes from <sysexits.h>
EX_TEMPFAIL=75
EX_UNAVAILABLE=69
cd $INSPECT_DIR || { echo $INSPECT_DIR does not exist; exit $EX_TEMPFAIL; }
# Clean up when done or when aborting.
trap "rm -f in.$$; rm -f out.$$" 0 1 2 3 15
# Parameter for $SPAMASSASSIN
# -P Pipe message, don't deliver
# -x Disable user config files
# -a Use auto-whitelists
cat | $SPAMASSASSIN > out.$$ || { echo Message content rejected; exit $EX_UNAVAILABLE; }
$SENDMAIL -i "$@" < out.$$
exit $?
- /etc/mail/spamassassin/local.cf angelegt mit Inhalt:
required_score 4.0 rewrite_header Subject ****SPAM(_SCORE_)**** report_safe 1 use_bayes 1 skip_rbl_checks 0 use_razor2 1 use_dcc 1 use_pyzor 1 ok_locales en bayes_auto_learn 1 # SUSE default ifplugin Mail::SpamAssassin::Plugin::URIDNSBL uridnsbl_skip_domain suse.de opensuse.org suse.com suse.org uridnsbl_skip_domain novell.com novell.org novell.ru novell.de novell.hu novell.co.uk endif # Mail::SpamAssassin::Plugin::URIDNSBL
- spamd starten und in runlevel setzen:
/etc/init.d/spamd start insserv spamd
- Postfix master.cf anpassen:
smtp inet n - n - - smtpd -o content_filter=filter:
...
...
# SPAMASSASIN
filter unix - n n - - pipe
user=filter argv=/home/filter/sc/filter.sh -f ${sender} -- ${recipient}
- Auto-Update der Bayes-Filter in /etc/cron.daily/spamassassins-update
#!/bin/sh /usr/bin/sa-update --channel updates.spamassassin.org
- Spamassassin-Installation überprüfen:
spamassassin -D --lint
- Sieve-Filter für SPAM-Emails einrichten, siehe auch Dovecot, z.B.
require "fileinto";
if exists "X-Spam-Flag" {
fileinto "SPAM";
}
