I am using Russel Nelson's POP3 before SMTP very successfully here on a
single server handling > 10,000 users.  I had to modify it slightly
though.  My tcprules update code makes sure that I have not already got a
rule that covers the new IP before adding it.

This works well and I will be expanding it in the next month to handle
multiple mail servers working off of a common tcprules set.  I will post
my results when I am done. :)
