I lost the whole maildir from my server fro 3 users. They all have iPhones with all the messages safely stored on the Apple Mail app on their phone. There is no way to export them/move them. Is there a way to get Dovecot to just download all the messages and folder structure from the client and restore it on the server? Your help is very very much appreciated. Thanks, ttyllc

Seen-Flag and Virtual
by Dieter Knopf 13 Nov '18

13 Nov '18

Hello, We have a very large folder structure (in a public namespace) on our Dovecot server and would now like to create a virtual folder containing all mails of the publick namespace. This worked quite well with dovecot-virtual, but the read status (\seen) is not preserved. i.e. when I read a mail inside the virtual folder, the read status does not affect the original mail. Dovecut was configured with per-user \seen-flag. Is it possible to synchronize the \seen-flag somehow? Thanks Dieter

Re: Cannot make disable_plaintext_auth = no works in configuration

Please keep list communications on list. If your doveconf -n doesn't reflect the changes you are making, then you are editing the wrong file.

moving only new mails from one server to another
by Nicolas 12 Nov '18

12 Nov '18

Hello, I think it is not really the right place to post about that, but lot of dovecot experts there ;) Basically, I have a server with dovecot 2.2.9 that has new (unread) mails (because of a bad DNS config at a migration time). Is there an easy way to move only these unread mails to a another server ? (no perms trouble here : all vmail:vmail) Though to iterate through all /var/vmail/*/*/Maildir/new and scp/rsync them. Would that work ? Thanks in advance for your time. Nicolas
