Cannot Authenticate to POP Server on ANY Mobile Phone

Moving a few Treo 700's from Alltel from Exchange to POP3 because of a company acquisition and I cannot seem to authenticate to the POP mail server.  When I send/receive on the Treo, it goes back to the screen where I have to enter in the password.  I know the server settings are correct and that the username and password I am supplying is correct... but it always asks me for the password again. I've tried replicating the settings on an HTC PPC6800 and the same issue arrises. If I replicate the settings to Outlook on a laptop... everything goes fine.  

Strange!

Any ideas as to what may be going on at the mail server? The mail server is sendmail but I do not have shell access.

Are you sure the password is right? A lot of those handhelds will auto-capitalize the first letter of a word. "Password" != "password"

Absolutely positive.

You mentioned using an exchange server, what version?

Have you checked the access controls on the pop3 virtual server? The laptop (assuming you were doing this at work) is probably on the same lan as the exchange server, but the phones will be coming from some public IP at the carriers datacenter.

The Exchange server shouldn't play a role because the POP3 server they are using now is in another state. If the desktops/laptops can connect to the POP3 server there is no reason the mobile phones should not. The laptops are used by field men so they are connecting from many different IP addresses.

Great ideas; but ultimately not the problem.

desktops/laptops usually use OWA and few computers use POP3 for anything.  Most exchange servers rightly block and prevent POP3 and actually don't even have the POP3 service running.
From one of these laptops or computers that supposed work "telnet servername 110" and see if you get a prompt.

About 20 desktop/laptops work (all of them). This was a company acquisition so they are moving from an Exchange server to a completely different and dedicated POP3 server (no Exchange whatsoever on the POP3 server) that belongs to the other company.

Is there some firewall that is blocking the IP range the phones use to talk to the pop3 server?

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.
