Flags/tags lost when moving e-mails to another folder
Hi,
I have an issue with e-mail tags/flags. The IMAP user is using Thunderbird or Roundcube with Thunderbird tags.
When the user (with an IMAP client) moves an e-mail from a folder to another, tags set on the e-mail are lost.
When we check the filesystem, we can see the "a" tag:
-rw-rw---- 2 test mailusers 2498 Dec 29 15:31 'cur/1676643827.M563793P15241.<HOSTNAME>,S=2498,W=2551:2,a'When we move the e-mail to another folder, the tag disappear:
-rw-rw---- 2 test mailusers 2498 Dec 29 15:31 '.test/cur/1676644340.M214404P22014.<HOSTNAME>,S=2498,W=2551:2,'In both folders, the dovecot-keywords file is:
0 $LABEL1The problem appeared after a major system upgrade (Debian 9 to 10). Dovecot version went from 2.2.27 to 2.3.4.1.
Some system informations:

Any idea of what I am missing? Could this be a bug in Dovecot?
Thanks in advance,

I faced the same issue and had to change from maildir to sdbox storage. The imap labels are now stored centrally per folder in an index file and not the filename anymore. Moving mails from one folder to another keeps the lable intact now.

Hi,
Thanks for the suggestion. I will give it a try inside a VM or something.
If I understand the documentation correctly, I need to change the mail_location variable for the whole server. There are a lot of mailboxes so I can't really change the format everywhere and hope everthing will be OK.
If there are any other ideas, I'd be glad to have it.
Thanks a lot,
