RC 1.5.x/1.6.x does not directly delete mail in shared folders

[Granada]

Dear colleagues!

We are proudly using Roundcube at the Medical University of Vienna since 2010 and we are happy the product exists. Now we've just (finally) upgraded our Mailfronteds from an old Cyrus 2.4.x to 3.4.x and from that moment on we have the following problem:

Users have access to shared IMAP-Mailboxes via ACL-Settings and some have the right to delete emails in these folders. If Roundcube is set to directly delete emails in one of these shared folders RC will move a mail to the personal trash and quit. It won't delete the mail from the shared folder anymore.

Marking mails for deletion and later compacting the mailbox works just fine.

Any ideas what went wrong?

The imap- and session logging of RC looks like this, the imap-log on the frontend-side looks alike:

In cyrus we have set "allowusermoves: true" - may this be a problem?

Kind regards

Setting no folder as Trash-folder under settings->special folders solves the problem halfway. Emails are being deleted permanently.

No solution, but it's not a problem of roundcube. Thunderbird has the same issues and it has to be something with the config of Cyrus.

I'd like to share the solution with you, as it may concern other users migrating their cyrus-murder-installation from earlier 2.4-versions to later ones. Cyrus announces MOVE and XMOVE and that does not work over the borders of each backend in your system. This is a very old problem and it has been discussed even by Alec back in 2016 https://github.com/cyrusimap/cyrus-imapd/issues/51, but the solution (or better say workaround) wasn't given. Just add suppress_capabilities: XMOVE MOVE to your frontend's imapd.conf and your done.
