Since I did the first commercial NAT box, should I stand in front of you folks,
or behind?

It seems cse.psu.edu is with boyd. It just stopped accepting my
mail, indirectly because of my NAT router.

It is now checking the helo domain.

Because smtp always puts sysname on the front of the domain
for helo, my machines say helo from an invalid domain, e.g.
cpu.9fs.org.

I've added an option -H helo to smtp to force it to pretend to be
something valid and DNSable.

I was tempted to put cse.psu.edu, because I thought that
might be valid, but instead settled for being honest and put
9fs.org.

Was there a different (software) solution that I missed?

Nigel

PS Since I live behind a NAT box, I'll join Presotto against
the wall later, but since he's licked the cigarette I'll bring my own.
