Postfix forwarded email Abuse

[127.0.0.1]

Hello everyone,

since two weeks we have some problems with forwarded mail to aol.

The problem is:

we have a virtual mail address benjamin.testuser@domain.tld (these has no postbox) and forward the mail to some.user@aol.com.

now some spammers detect the mail on our system and send mails to this address.

so aol maked our email server as origin of the spam.

how i can say postfix that he must use spamassassin to check that kind of outgoing mail (orig_to)? any idea?

we have a running syscp installation with postfix and spamassassin via maildrop module.

my first thought was: added smtpd -o spamassassin in the postfix master.cf. but the mailserver break down and double checked every mail because of maildrop.

hope for response

You could install amavisd (see http://www.howtoforge.com/amavisd_postfix_debian_ubuntu ), but I don't know if this configuration is supported by syscp.
