I've noticed that a couple of folks with external imap accounts receive the following error (in image) when logging into the zwc. After logging in, choosing the "get external mail" button tends to pull in their mail again. It does not happen to all imap accounts, but it always happens to the same accounts, and I have not found a correlation between them (all sorts of different servers, different users, different settings, etc).
Nothing relevant appears in the mailbox.log on the server, just the user end.
Anyone seen this before, or have any thoughts on where to look for more info?
