hi list,
I want to reject outgoing spam from my server.
Users, aliases and domains come from LDAP, postfix uses
smtpd_sender_restrictions = reject_sender_login_mismatch
However, I did not quite figure out to handle incoming spam different from
outgoing.
i want something like
if (sendermaildomain = one_of_my_domains){
$final_spam_destiny = D_REJECT;
} else {
$final_spam_destiny = D_PASS;
}
I found various things to bypass scanning of outgoing mails, but no solution
for my case. Mail is sent only via port 25, clients come from dynamic
ipadresses.
Or is it possible in postfix to use different content_filter for incoming and
outgoing mails? ... I could start 2 amavis instances on different ports, one
handling outgoing and one handling incoming mails, however I don't know how to
configure this in postfix or distinguish incoming/outgoing mails.
thanks in advance,
infoomatic
