Seems like a useful diagnostic feature someone left turned on.

Shades of Novell.

Still sounds like Novell!

I think Greg Woods used to run some sort of DNSBL on rfc-compliant.org
that folks could use to publicly shun sites that don't accept mail at
postmaster at .  I wound up on there accidentally due to a full disk once!

As much as I'd like to block mail from all companies in the "Big Tech"
cartel, too many people I actually need to correspond with have webmail
accounts on those services.

I've mostly stopped blocking domains by name because of how much spam I
got from domains that were a day or two old.  A few DNS-based heuristics
send most of the annoyances away (fly-by-night operations often fail to
give a reasonable hostname in EHLO).

We're going to end up with a parallel Internet if we want those days
back.  Far from a bad thing, it seems like part of the intent of the
original protocols--once you let everyone into something with such
"market potential," of course the suits and scammers are going to
entrench themselves.

I'd love to never receive mail from another Google, Microsoft, or Apple
domain ever again, but, again, there are just too many people I interact
with who were tempted by the free cheese in the trap.
