spam filter nicht im Eingriff (postfix - amavis - dovecot)

Christoph Kukulies

Irgendwie kriege ich mein Spamfilter nicht ans laufen. Es kommt mir vor, als bekomme es gar keine Mail zu Gesicht.


Hier sind mal meine

main.cf und master.cf:

myhostname = mail.mydomain.org
mydomain = mydomain.org

smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)

Wenn ich den virtual_transport spamass-dovecot einschalte, bekomme ich "too many hops" vom Server, wenn ich von außen eine Email zustellen will.

Mein host hat den Namen mail.mydomain.org. IN meine /etc/hosts steht zwar auch noch (Ubuntu Eigenheit?)

127.0.1.1 mail.mydomain.org

aber wenn ich den Host auflöse

# host mail.mydomain.org

bekomme ich die IP, über die er im Netz von außen zu sehen ist


Hilfe willkommen,


Grüße

Christoph
