We’re currently in the process of upgrading our IMAP server software. It appears that there is a small incompatiability problem with some IMAP clients causing connections for affected users to be immediately terminated. This appears to be affecting a few dozen users at the moment and we’re investigating why and hope to have a fix shortly.
Update (by robm at Tue Oct 16 07:20 UTC)
We believe we’ve worked out the cause of the problems and have fixed the IMAP server software so all users should be able to login and work normally again.
