Thats whats getting my goat.  Te guy is subbed as
@hcc.mass.edu.  Majordomo/sendmail, when they resolve the address to
send the email, get @hoc.mass.edu.  I can't find any reference to hoc
anywhere in the dig queries.

A side note, sendmail is also rejecting mail from this guy because his
domain doesn't resolve.  Does sendmail only check A records for domain
validity?

If it ca be proved those errors are what are causing the problem, I'll
tell the guy that.  What is weird, is that my regular mail service can
deliver to him just fine.
