It's exactly the fact that you don't have a name like 'foo.bar.int'
with dots in it, funnilly enough.

sendmail(8) really, really wants to be able to look itself up in the
DNS -- after all, in order for anyone to send you e-mail across the
internet, you've got to be able to be found in the DNS...

Now, clearly this is an internal mail server, so you don't actually
need to enter your servers' name into any sort of DNS.  (Although
running an internal DNS is actually a pretty useful thing to do, and
not as hard as you might think.)  But you will need to invent a domain
style name -- something like 'bsdsrv1.mydomain.internal' and enter
that into /etc/hosts. You should put it on the same line as the
'bsdsrv1' -- something like:

    192.168.0.1     bsdsrv1 bsdsrv1.mydomain.internal

This will mean that your internal e-mails will default to
'[EMAIL PROTECTED]', but that is something you can
tweak the sendmail configuration to change.

Note that the hostname on Unix systems is not case sensitive, and is
traditionally all lower case.  It's also the case that the Netbios
name that a windows machine may use need have nothing to do with the
actual hostname, although it does get very confusing if you don't
synchronise the different names.

        Cheers,
