Irgendwie kriege ich mein Spamfilter nicht ans laufen. Es kommt mir vor,

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,
