This is, what the logs say, when i move a message to another folder with thunderbird drag&drop
Dec 04 17:22:24 mymail dovecot[16982]: imap(user.name)<17010><XtHsqjR8JqbV0J0m>: copy from INBOX/Arbeiten/bla: box=INBOX, uid=849, msgid=<a133b9b2-6913-14e8-f509-b6c81750e...@bla.com>, from=Full Name <u...@bla.com>, subject=TEST005, flags=($label3 NonJunk) Dec 04 17:22:24 mymail dovecot[16982]: imap(user.name)<17010><XtHsqjR8JqbV0J0m>: expunge: box=INBOX/Arbeiten/bla, uid=7, msgid=<a133b9b2-6913-14e8-f509-b6c81750e...@bla.com>, from=Full Name <u...@bla.com>, subject=TEST005, flags=(\Seen $label3 NonJunk) So i think, there is a Problem with dovecot. Is it possible, that a misconfiguration causes such a behaviour? It is only the \Seen flag which is removed and obviously the \Recent-flag, which is set, when i move a message to another folder. All other Flags can i set/remove with sieve-filters. Maybe these flags are set correctly, but then is another process, which removes the \seen and sets the \recent flag on every new message in a folder...
