Recently we have upgrade Zimbra to Release 8.8.6.GA.1906.UBUNTU14.64 UBUNTU14_64 FOSS edition and my setup is 2 MTA (mail01,mail02) and 3 Mail store (mail05,mail06,mail07).
We have report that some of our users who is using Thunderbird 45.7.1 and 59 beta 2, when they move emails from
1. their own account's Inbox to a subfolder,
2. their own account's Inbox to a mounted account's subfolder,
3. mounted account's subfolder to another mounted account's subfolder,
when they go to the target folder to check, the email are not there but when they login to Zimbra Web mail to check, the emails are there.
When they perform this copy/move operation, they will get this error message:
The current operation on "Folder" did not succeed. The mail server for account firstname.lastname@example.org responded: mail05.domain.com Zimbra IMAP4rev1 server closing connection.
This only happens when the user is using Thunderbird, when we use Outlook 2012 to view the affected folder, it shows the same thing which is the mails is not there. In Zimbra Web Mail, we do not face this issue.
We tried to check in the mail server logs but we cannot find any indication of this error.
On the servers, these are the setting we have set:
Code: Select all
| zimbraImapMaxConnections | zimbraImapNumThreads |
mail01 | 200 | 200 |
mail02 | 200 | 200 |
mail05 | 1000 | 1000 |
mail06 | 1000 | 1000 |
mail07 | 1000 | 1000 |
Is anyone facing this issue? How do we solve this?
Thanks & Regards.
