My mutt command is running slow. it takes 30 seconds to a minute to go

I am running AIX 5.1 and I host my own internal email server.

I think it has something to do with the way it is locating my email
server to send or the way my email server is accepting connections. I
am not really sure where to begin.

I have been having problems with my email server the last few days so
that is most likely where the problem is. It is running Redhat 8.0. A
friend of mine got it working for me, but he hasn't had time to show me
the changes he has made yet.

Any ideas?
