There's no configuration like what the expire timeouts are or anything.
My first idea, that hit me after reading through the whole post, was to
keep track of all mailboxes of all users and issue the commands later.
The plugin saves just one value per physical mailbox, when a) the first
message arrives an empty mailbox or messages are expunged? Or each time a
message is received. What would be the impact of monitoring all mailboxes?
There will be a new doveadm command:
doveadm expunge [-u user | -A] <mailbox> <search query>
What about shared mailboxes and namespaces? Can "<mailbox>" be a phyiscal
path rather than a IMAP mailbox name?
So when you want to expunge all mails from Trash older than 1 week for
all users, you say:
doveadm expunge -A Trash savedbefore 1w
TODO:
- When using multiple mailboxes it would be more optimal to handle all
mailboxes for a user at once, rather than using separate doveadm
commands. Maybe the command syntax needs some more thinking to support
this. Different mailboxes could have different rules though..
Hmm, does doveadm support to read commands from stdin / file?
If I imagine such scenario with some hundreds of users having configured
expire for some folders, that leads to plenty of process creations etc.pp.
doveadm <<EOT
expunge -A Trash savedbefore 1w
expunge -u user1 INBOX savedbefore 1y
expunge -u user2 INBOX savedbefore 1m
EOT
