RE: [Nolug] sendmail relay problem on LAN

Apparently the mail relay can't resolve domain.com. Check your zone
files and/or try restarting your DNS server.

Oh, I forgot. Our domain name is hosted in California. My local box is
relaying outgoing mail. The domain.com is not pointing at my client's
DSL. I
pointed domain.dhs.org at my box for my convenience, only.

I know someone was going to ask about it, heh.
