Mail problem

[Paul]

Hello,

I am having some troubles on a server that is running CPanel. For some reason, peoples emails are getting delayed. They will send them out, and for some reason or another it will take a couple of hours to finally get delivered. This is not a problem for local addresses, those are delivered instantly. The server is running Red hat 7.1

Any ideas on why this would be happening?

ok, first off what MTA are you using

Sendmail, Exim, Qmail, Postfix?

Let me know.
