Hi fellow Zimbrans,
I'm confronted by a mysterious problem: one user stopped getting new messages in her inbox. /var/log/maillog shows that the messages are received normally and zmmsgtrace also reports delivered messages, but they never show up in the user's inbox.
This started six days ago, before that she was able to receive mail normally, and she can still see the previously received messages in her inbox.
I'm baffled, because everything seems to be normal, but mail just doesn't appear where it should. I've tried reindexing her mailbox to no avail. As a rather green Zimbra admin I'm at a loss where to check next, please give me some pointers!
