The most common form of bounced mail is one that sends back all the headers that were sent with the original mail.

vBMail adds a specific header which it then checks for in the bounced mail body. If found, it does some validation checks, and if it's valid it flags it as a bounced mail.

Those bounces that do not follow this standard are either discarded (Automatic mode) or flagged as Unknown Mail (Manual mode).

For maximum "cleanliness" you would set it to Manual mode, then manually edit each mail that did not follow the aforementioned standard, ensuring the mail address is correct (for instance, mails that have been delayed 24/48/72 hours will show as originating from Mailer-Daemon@yourdomain.com instead of the bouncee) and setting the bounce flag to yes.

My site benefited greatly from restricting accounts with inactive email addresses. Spam and trolling went down drastically.

That is not currently possible, due to the fact that there's a chance for false positives (i.e. people using their own domain name's emails, and their site had a temporary problem, or their data center has issues receiving mails from any IP from another data center - this is a real concern, we had this exact issue with Mokonzi himself over there) which would have an adverse effect on a forum.
