Umm, you are. Kind of. It's not related to the email address. Not really.
My email address gets rewritten by my MTA to be setantae@submonkey.net since
setantae@rhadamanth.private.submonkey.net isn't deliverable outside of this
room (and setantae@pc4-card4-0-cust162.cdf.cable.ntl.com is a bit hard to
remember and wouldn't be deliverable either :).
However, I was in a situation where I couldn't send mail directly to
hub.FreeBSD.org because my MTA kept announcing itself with
"HELO rhadamanth.private.submonkey.net", which doesn't resolve as far as
the internet is concerned. I had to configure my MTA to do
"HELO rhadamanth.submonkey.net" instead before my mail would be accepted.
This is the kind of thing I'm talking about getting added, and it's not
really anything to do with my email address.
Now it's a slightly fine grained point, maybe, but there's certainly a
difference. It may be slightly easier to just say something like :
"As required by RFC 2822, your announced hostname must resolve."
I'm just not sure.
