Cannot Receive email

Hi maybe you guys can help resolve this problem. Our company has recently installed Windows 2000 and a firewall. Since this installation, we have been unable to receive pop3 email through programs such as outlook express and Goldmine, a contact manager that we use. We are sure that there is no problem with the email program, (it has been re-installed, tested, turned inside out and back again. We are also sure that the ISP is not the source of the problem as we have tested it from other locations and its fine.
We have tested the communicatiuon with telnet which gives OK. We have allowed port 110 and the ISP server on the firewall, but all to no avail. We can send smtp mail correctly, but when it comes to receiving, the log in is correct and we even sometimes get the email header threough, but then it just stops. After a while we get a timed out message.
By the way, we also cannot download newsgroups into outlook express, but we can download via ie anything you want.

Any help would be fantastic, as this problem has stumped all other sources of technical support.

Sounds like it could be a firewall issue.

The best thing to do would be to troubleshoot your firewall by opening up a huge whole for ALL traffic and see if the mail works. Just open it up temporarily, then close it.... or better yet, take down the firewall then bring it back up.

This will tell you for SURE if it is a firewall issue or not which is important to figure out before you troubleshoot any further.

Newsgroups sounds like a firewall issue too - that uses port 119 I think?
