Cannot move emails using IMAP

Postby bb101 » Fri Jun 29, 2018 5:39 am

We have been running Zimbra Network Edition with minimal issues since v7 and have progressively upgraded to the current version 8.8.8. Our mailbox users have recently noticed that emails moved using IMAP do not reflect properly in Zimbra Webmail and ActiveSync. Zimbra receives the request and updates the IMAP client (Apple Mail in our case) so the email appears to have been moved within the client, but it just remains in the original folder on both Webmail and mobile devices. Moving an email to another folder using Webmail or ActiveSync works perfectly however, and updates the IMAP, webmail and ActiveSync clients immediately as expected.

I have raised the issue with Zimbra support and they are currently looking into it. Worryingly, their engineer is starting to poke fault at the IMAP protocol itself and is saying it might not be fixed:

"I have done the tests and what I have found out that it is an issue with IMAP protocol. In imap it downloads only the headers, so moving a header is not equivalent to moving a message. Hence when you move a folder in imap it does not sends any request to ZCS server for the move soap request."

Also please understand this is not a issue with zimbra, it is how imap protocol works. We are not having any control over the functionality of imap we are just using the imap protocol as defined.

I doubt this can be fixed as it is dependent on an product which we are not in control of. I will still open an internal escalation on your behalf and wait for managements decision.


As Zimbra has worked fine with IMAP up until the recent version, I imagine this is a recent bug introduced into 8.8.x. If Zimbra cannot (or chooses not to) support IMAP properly then I am not sure what future it has a mail server?

Is anyone else also experiencing this issue?

Does this also happen using a 'fat' IMAP client such as Thunderbird? Anything in the log files that indicate any problems?

Hi Bill,

I just tried moving a message within Thunderbird, and it moved the email successfully for all IMAP, ActiveSync and Webmail clients.

Doing the same thing using Apple Mail, the email is copied to the new folder but not deleted from the Inbox (so it ends up existing in two folders at once).

We never had this problem prior to a recent version of Zimbra -- I wonder if they have changed their IMAP routines?
