MX records are the norm. There is even a constituency in the email ops
community that believes use of A (and AAAA) records should be deprecated.
In any event, the kind of anti-abuse techniques that are predicated on having
abusers be lazy or sloppy has, at best, short-term benefits, because the bad
actors are quite good at adapting.

Discussion, please. See below for my take; the IETF is one host, MX is really meaningless, and there are benefits to avoiding a ton of spambot zombie spam.

Thank you!
Regrettably, we got many MANY complaints in the past from IETF community
members who objected strongly to the absence of MX records. So although
I personally feel as you do, I cannot make the suggested change at this
time.
Perhaps the spirit of things has changed. You are welcome to bring this
up on the IETF list if you want, and to quote this response. Having
been beaten down once, I'm not prepared to fight that battle again just
yet. :-)

mail.ietf.org. is ietf.org., so you can remove your MX records for
ietf.org. This should cut down on spam since a lot of spambots
will skip over domains whose MX list cannot be obtained. Real
mailers will of course fall back to A/AAAA as per RFC 2821/5321. A
few hosts will have trouble, but very, very few indeed, and that
isn't your (our?) fault.
Cheers,
Sabahattin
