    I need to figure out where a bunch of SPAM is coming from so I can kill it. I have ran rkhunter and all is good. I guess I'm hoping that I can access a log that will show me exactly where the SPAM is coming from. We have a few forms on many sites on this server so it's hard to see where it is coming from, here is a snippet of the mail.log.
    Code:

    If you would have used php-fcgi and suexec, then you could see from were the spam is coming as each site has its own user and php runs under that user.

    As you use mod_php, another option is to inspect the emails in the deferred queue with postcat, current php versions are writing the name of the file which is sending the email in the mail header.
