Cannot receive External POP3 Email

I have been informed by my client that they cannot receive external
pop3 email.

They can send out to recipients, but not receive a reply.

They only have 5 users and have an external company provide their
website and email. I have contacted the external company who inform
me there are no issues.

I have checked the following

Server Management

Internet and Email

Connect to the internet

Left all the other settings as they were

Enable Internet Email

Use DNS to route e-mail

Use the Microsoft connection for POP3 Mailbox

Email domain name xxxxxxxx.com

Pop3 mailbox

mail.xxxxxxxx.com
Port 110
user name - correct
passwords - correct
sending to correct Exchange mailboxes

Enable exchange to remove attachment.

I have also tried disabling the firewall but no difference.

The server has 2 NIC's

Any ideas?

Regards

Trevor
