OK. Subscribed and voted, but the bug should point to "where to start" in
Dovecot's documentation.
Ok, but... where would that be? I don't see a 'Where to start' to point to...
And, well, if subscribed and voted, you could easily add that yourself, no? ;)
This isn't going to happen in thunderbird, outside of someone writing
code for thunderbird to login to the dovecot server (via SSH with an
admin/root password), find the dovecot config files on the server
(which will vary based on each server), edit the dovecot config
non-interactively, and then be be able to restart the dovecot server
to make the changes stick (which, again, will vary based on each
server). I would guess there is about a none percent chance of that
occurring.
You can read what he says in this very thread. I'm not a google+ user either. He just says Dovecot's virtual mailboxes are intended for admins only, not for clients. It doesn't sound logical, but that's what he says.
This is exactly what I said previously in this thread. And it is a
100% accurate statement.
The ONLY way this can be implemented client-side is if there are some
sort of standardized IMAP commands that the client can use to alter
the mailboxes. There isn't.
In general, IMAP 4 doesn't allow a command to work on multiple
mailboxes at a single time (outside of MULTISEARCH... but that's one
reason why MULTISEARCH is experimental and really hasn't provoked much
interest). That's why virtual mailboxes don't conceptually work very
well as a server-level entity and instead make much more sense as a
client-level feature.
