Could someone knowledgeable in NFS help me out please?

I am neither a network administrator nor a Unix guru.  I recently began
working in a new facility and my email is slightly screwed up.  When I send
email, the header actually contains my hostname and domain name (as it should).
When the recipient replies to the message, the mail bounces, since the
server here at my end, for whatever reason, does not recognize my host/domain.
The typical error message reads "Illegal host/domain name".

I've repeatedly asked for help from my network guy, but thus far he has been
unable to correct the problem.  I'd be happy to shift the discussion to 
private email or telephone if anyone would be willing to help.  I can send
a copy of our sendmail.cf file or whatever else may be of help in solving
the problem.  I'm running SunOS 4.1.1 on my SparcStation IPX host.
The server is a Silicon Graphics Iris Indigo.

If this is the wrong newsgroup, I'd appreciate a gentle prod in the right
direction.  Thanks.
