For the most part my home doesn't bounce mail, it discards it.

But it keeps a copy of all mail in a file. I run a daily report against
the Postfix syslog file for discards/rejects, and if any look like false positives, I examine
their content in the saved file, and resend the mail and repair the blocking as necessary.

However, my system is somewhat unique in that most of it's email is fetched
from POP3 accounts at various ISPs, and injected into Postfix using Postfix's
XCLIENT feature. The copy is not made by Postfix itself, but is made before being injected
into Postfix.

I do run Postfix RBL checks on both the injected email and the mail arriving directly
via the Internet. I guess I've done it long enough and adjusted configurations long enough
that there are seldom any false RBL positives. If I do find one in the logfile analysis, I'll
just fix the block, and ask the sender to resend their message.

At work, where there are millions of messages, there's not enough time in the world for
administrators to manually examine a trash pile. It's just assumed that eventually the
sender will complain to their admin or counterpart at your company, and the issue will
work it's way to your desk.
