I hope you followed that. It is no big deal yet, because usually all the

Stop there. You are sending bounces to spam, instead of just rejecting
it at SMTP time? Fix that first.
When I know it is spam, I just reject and discard it. However, I can't
be sure it is spam just because the recipient doesn't exist. Often,
legitimate users misspell email addresses. At some sites I use a content
filter (DSPAM wrapped for Python), but this has its own problems with false
positives.
