Today, mysteriously Zimbra Desktop stopped receiving mail from one of my three non-Zimbra email servers. The email server that it stopped downloading from, can still communicate with Zimbra Desktop to send email, but for some reason ZD is not downloading the emails anymore. Has been working for about 2 weeks, then this afternoon - poof! I had setup some folders for filtering emails to. Originally they were separate folders from the inbox, but mistakenly I put one of them into the inbox. Once I saw it in the Inbox folder, I moved the other folders there too as it seemed to make sense to have them all as subfolders to the inbox. Would this have anything to do with the problem?? Communication (two way) stopped right at about this time.
