I see many many pop3 scans and all it takes is guessing just one login/password and here comes the spam and/or viruses. And if you were scanning outgoing email, you can catch this before you are blacklisted.
Scanning outgoing email is not just a simple matter of trusting your own users. It's part of a good security plan and acknowledging that something can happen and it makes sense to scan outgoing email to make sure it's trusted just like you do to incoming email.
