I really need your help. My Postfix server is sending out spam (I know it's real because I received one myself). It seem to have started on December 19 2009.
I've followed the howto's to set up a secure postfix server, as far as I could without limiting the options beyond my needs.
I'm sure I've got SSL, TLS and no relay running, but it still spews out spam.
I turned it back on for about an hour and got over 1000 lines in my mail.log.
I'm not an expert, so I could really use some help to stop this and secure my mailserver. I have a web shop, so www-data has to be able to send mail.
Please let me know what other info you need. The mail logs can be found here (since they're too large to upload):http://heksebua.com/logs/mail/
