Webmail authentication issues post software upgrade (resolved)

Message

One of the things upgraded this morning in POA HF02 was courier-imap on the qmail cluster machines. Seemingly there's an issue currently with IMAP, pop3 remains working at least. We're investigating the IMAP issues and we'll hopefully have a resolution sooner rather than later.

This applies to all IMAP connections made to mail.blacknight.com

Update: 11:12am

Webmail + IMAP should be back now. We don't know why this issue cropped up this morning, but it looks to be related to the nfs servers clock being off by 4 minutes and IMAP doesn't like the time skew. We've setup ntpdate to run every day on the NFS servers now so this problem shouldn't reoccur.
