Hi,

I've been looking for a email server to place onto my QNAP NAS, and the only supported package seems to be XEAMS, so I've installed it.  I've managed to get SMTP and POP3 working, however IMAP is refusing to pull messages from the server.

Having enabled logging for IMAP, checking the logs I can see the following;

Has anyone seen this issue before?

The QNAP box is running Java 1.8 if that makes any difference.

Many thanks
