Access POP3 or SMTP Servers - Permission denied

[lil]

Hi

I've built a server with Centos 6 and installed Osticket 1.6.

I'm at the email stage no matter how much I try and cannot get email bit. it keep coming up with

[SMTP: Failed to connect socket: Permission denied (code: -1, response: )]

and

110: Permission denied - Invalid login. Check POP settings.

However if I telnet from the cent os server I can see the pop3 server.

I've confirmed the username and passowrd are right, on the pop info, as I used mail2web.

Any ideas? - I'm fairly new to cent os, so it maybe an easy fix that I haven't looked into.

Thanks
Lil
