Hmm ... I seem to have not received a mailing list posting:  I've
never seen the text that Ken quoted.

I'm pretty sure that Comcast would be willing to provide me with
my own FQDN (*.comcast.net, or possibly an "arbitrary" one) for a
fee.  Maybe even for free.  But I never looked into the option
since I've never needed one outside sending emails.  (That is a
very important need, granted, and maybe I should.)

Google may also do the same (though not "*.google.com"), but not
as part of GMail.

As for Ken's "Thirdly" note:  I can't disagree with you.  Sadly,
Stanford has invested heavily in using Proofpoint, and are not
likely to change until maybe the university president starts
missing email.  (Though, in that case, they'd probably just make
an exception for him.)
