First, I hope you're running with the latest updates, and not really RHEL
5.5.

It's not really possible to know exactly what is wrong from these somewhat
vague details, but I suggest looking at your DNS settings, particularly for
the hosts running sendmail.  As a quick guess: Sendmail is very picky about
DNS and if you are using any host names that don't resolve, it can take
longer than it would otherwise.
