One of our Zimbra users complained about Zimbra is telling him, that he is "over quota" although there are only some messages in one of his folders.
When I log into the users account, I can indeed see only ~10 msg. in the spamfolder, but the quota is exceeded.
zmmailbox -z -m <account> gaf
tells me, that the user has about 1200 msg with ~50MB in various folders. I can not see the messages... Not through the Webinterface and not through IMAP.
I made a full backup for the account, which resulted in all 1200 msgs being dumped... So the messages are there - but not to be seen by the user.
There is one "suspicious" filter for the account. The user tried to automatically move some messages to the spamfolder. But he has accidently setup the filter in a way, which will move any incoming message to the spamfolder.... I dont know, if this is related to those invisible messages.
What is going on there? How can I track the problem?
Even if I try to restore the account from backup (to a new account), the problem persists....
