Have you fiddled with /etc/sendmail.mc? This may or may not be similar to
what you are dealing with, but I'm on a dialup at home, and of course I
use a bogus DNS name to get sendmail to behave. But some systems (notably
UIUC's, where my friend is in graduate school), won't accept mail
originating from an unverifiable FQDN. So I wrote a new sendmail.mc to
relay through a machine here at the Soc. Science Research Facility at the
U. Then it was 'm4 sendmail.mc > sendmail.cf' and bingo. No more bounced
mails. 

I don't understand sendmail very well so it's likely that I'm doing
something wrong...but I couldn't solve the problem simply editing my
headers in mutt, I had to muck with sendmail.
