What about this log indicates that your SMTP mail server (postfix) is relaying email? All this shows is that your mail server tried to deliver a message to a verizon mail server, and that they rejected it. Who is the sender of the message to [email protected]? Who/what injected the message? If indeed the message was relayed by your server, there should be an entry in it's smtpd log indicating this. If you feel you have configured postfix correctly, then I would look elsewhere. I see you have PHP running on mail.caandb.com. I would start looking for a hijacked PHP script.
