Problems with IMAP / Thunderbird

[tobias.dinse]

Hello,
The last days we have more and more the Problem that some (not all!) E-Mails on only one Mailbox cant be deleted over Thunderbird by using IMAP.
zmcontrol -v

Release 7.1.3_GA_3346.UBUNTU10_64 UBUNTU10_64 FOSS edition, Patch 7.1.3_P1.
The Client uses Thunderbird ESR 10.0.9 on Windows XP SP3. After deleteing or moving the Mail over Thunderbird it will be back after about 2-3 seconds again. In the Zimbra WebGui the Message was deleted / moved successfully.
Mailbox.log:

INFO [ImapSSLServer-49657] [name=user@domain.com;mid=34;ip=82.100.195.18;ua=Thunderbird/10.0.9;] mailop - Performing IMAP copy of Message (id=182109): copyId=182629, folderId=3, folderName=Trash, parentId=-182109.
Is there no Error in the Logfile when I try to delete an Mail with ID "182109" that does not exist?
regards
Tobias

Been a long time since I've used Thunderbird with Zimbra, but if I remember correctly Thunderbird lets you choose a folder for deleted items. Maybe a misconfiguration on the client end? Just a thought.

I have already checked this Option. Also I tried to use the Setting to "directly delete" the E-Mail without moving to Trash or else. The Mail is getting loaded from the Zimbra Server again.
