I have set up a Ubuntu, Postfix, Amavis, Courier, Maildrop mail-server. My previous mailserver was working perfectly, but this won't rewrite spam to "email@example.com" to "firstname.lastname@example.org" When I send mail to "email@example.com" it drops down in my Spam folder, so maildrop+postfix is working correctly. The problem is that amavis is not rewriting the recipient.
