Two questions:

1) what is comp.std.misc?

2) not knowing what current SMTP-related standards are currently
in-place now, or how these various details of RFC 7208 work, will the
SMTP software that my server has been running for the past 13 years
(Post.Office, circa 1999/2001) continue to be able to send and receive
mail to external hosts on port 25? Because that's all I really care
about.

Forged or not, my server has almost 10,000 entries in it's IP-based
SMTP-blocking list, with 90% of those entries being /16 ("B class")
entries, and add to that I have about 2-dozen /8 "A-class" entries.

So I block a good chunk of IPv4 IP space as it is, and I see hundreds of
SMTP-Connect-Reject entries in the daily log files.

There is no better anti-spam method then your own heavy-handed IP
blocking list.

I should at some point see if trojanized spam relays are still baffled
when there is no MX entry for their target recipients like they were a
few years ago.
