Our setup: 2 replicated dovecot 2.2.33.2 servers thunderbird client When I select more than one mail subfolder in thunderbird and drag & drop them to another subfolder only one subfolger is moved. In the following I can't move another mail folder to the first target. Any ideas why this happens? best regards, arno -------------- next part -------------- A non-text attachment was scrubbed...
