dovecot

I have a problem with Dovecot + Postfix. My server is sending SPAM from the local user "dovecot", but my server is not configured as an open relay (mails can be sent without auth-ing only from localhost). Also, nobody except me, has SSH access to the server.

How can I find what exactly is triggering all those SPAM mails? How can I get something like a backtrace that shows what exactly happened the moments before a SPAM email got in the queue of postfix?
