SMTP connections timing out

[Albert Hopkins]

I have two qmail servers which are load balancing for our domain, however,
one of our
servers is taking a long time to respond.

If I telnet directly to port 25 I immediately get a connection, but it takes
over a minute
to get a 220 reply from the server.  The log files show nothing out of the
ordinary.  Both machines are on the same network with the same
configuration.   Anyone have any idea how I can figure out what qmail is
doing to take so long to respond?
