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.
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.
