The strangest problem I've ever seen
Just moved an account from an older Linux box to a new FreeBSD machine. Customer puts in a ticket to complain about her email not working. No problem, I think to myself... pretty common stuff with server migrations and customers that just need to alter a setting or two.From my last ticket response to the customer:
1. Your email worked (ie downloaded to Outlook Express) immediately before we moved your account to a new server.
2. We've demonstrated that email is going to the new server. Evidence of that:
A. I've verified that our servers are reporting the correct IP address for your mailserver and your domain.
B. You've verified that you can ping [your domain] at the correct IP address.
C. You can log in to webmail with no issues and get email sent to your domain.
D. We've watched email be delivered via the exim mainlog.
3. I have created an account using your credentials and mail server names in Outlook Express and have been able to download copies of your email (while leaving copies on the server so you don't lose anything).
4. You have no issues with any portion of your site except the ability to receive email via the POP3 protocol, even after deleting and recreating the account in Outlook Express.
If we hadn't gone to the lengths of deleting and recreating the account, I'd say the only option open to us was that you had your POP3 server set to the IP address of the old server. Having eliminated that as a possibility, I'm afraid I really don't know what else to look at. We've checked logs, IP's, tested every facet of the system and it all comes back working for me, but not for you.
So... I'd love to hear any and all theories on this one... I'm completely stumped. Probably something simple... it is 5am and I've been on this for about 4 hours now.
