Hallo,
ich habe hier unter Debian Postfix mit Amavis (+clamav, +spamassassin) laufen.
Leider erhalte ich trotdem pro Tag ca. 5-10 Spammails, die sich durch den Filter mogeln. Komischerweise ähnenlich sich manche Mails von Zeit zu Zeit, und obwohl ich sa-learn aktiviert habe, scheinen sie zu niedrig getaggt (X-Priority 3) werden.
Grundsätzlich funktioniert der Filter ganz gut, da oftmals mehr als 6000 Mails pro Tag "rejected" werden. Mein Ziel ist es nun das System so zu konfiguieren, dass max 2-3 Spammails durch den Filter rasseln.
Ich bitte Euch deshalb meine Konfigurationsdateien einmal durchzuschauen, und mich auf Fehler und Verbessungsvorschläge aufmerksam zu machen.
Hier mal eine Liste mit Konfigurationsdateien:
/etc/amavis/conf.d/20-debian_defaults
$QUARANTINEDIR = "$MYHOME/virusmails";
$log_recip_templ = undef; # disable by-recipient level-0 log entries
$DO_SYSLOG = 1; # log via syslogd (preferred)
$syslog_ident = 'amavis'; # syslog ident tag, prepended to all messages
$syslog_facility = 'mail';
$syslog_priority = 'debug'; # switch to info to drop debug output, etc
$enable_db = 1; # enable use of BerkeleyDB/libdb (SNMP and nanny)
$enable_global_cache = 1; # enable use of libdb-based cache if $enable_db=1
$inet_socket_port = 10024; # default listenting socket
$sa_spam_subject_tag = '***SPAM*** ';
$sa_tag_level_deflt = 2.0; # add spam info headers if at, or above that level
$sa_tag2_level_deflt = 6.31; # add 'spam detected' headers at that level

$sa_mail_body_size_limit = 200*1024; # don't waste time on SA if mail is larger

# Use D_BOUNCE to generate local bounces by amavisd-new
# Use D_REJECT to generate local or remote bounces by the calling MTA

#
# Whatever you do, *NEVER* use D_REJECT if you have other MTAs *forwarding*
# mail to your account. Use D_BOUNCE instead, otherwise you are delegating
# the bounce work to your friendly forwarders, which might not like it at all.
#
# On dual-MTA setups, one can often D_REJECT, as this just makes your own
# MTA generate the bounce message. Test it first.
#
# Bouncing viruses is stupid, always discard them after you are sure the AV
