Posting by Email Problems

I am trying to set up the Post via e-mail function found in the “Writing Options” tab. However, I can’t seem to get it to work. I have noticed that the default port is set to 110. Does anyone know if this needs to be changed for any reason? The email I am using I set up through Cpanel’s “web mail” and I copied all of the POP3 account informtion perfectly but there was no mention for a port setting.

Any thoughts?
