Email login issues after 11.40 update

Immediately after the server was updated to 11.40, I started to have login issues.

I have several accounts on the same server, and access the IMAP ones via Thunderbird, and the POP3 ones via Outlook. The minute the update hit at midnight, I could no longer login to mail consistently. Both Outlook and Thunderbird keep asking for passwords, as they can't login.

Did a setting change somewhere? I'm doing something else right now, copying an old IMAP from another server to this one, so it CAN login. But it gets pissy with more than 1 concurrent login. Did the update push through some kind of max connection per user or something? Or did it add/change something in WHM?

What gives?
