I'm interested in replacing my cron script that expunges old deleted mail with the new feature announced in 2.2.20

• Added mailbox { autoexpunge=<time> } setting. See http://wiki2.dovecot.org/MailboxSettings for details.

To use it, I need to specify which mailbox needs them using the namespace configuration. For example

namespace inbox { mailbox Trash { auto = no special_use = \Trash autoexpunge = 7d mailbox_list_index = yes } ...

mailbox_list_index=yes is a global setting. You can't have it here.

Oh, yes. Thanks for pointing that out. By the way, what does it do? The wiki states

mailbox_list_index=yes can help a lot by replying to IMAP STATUS
(and similar) lookups from a single index without having to open
each mailbox index separately.

So it create an uber-index that combines information from individual indices? Are there any drawback to using this?

1. Do I need the special_user configuration at all? Will some clients start using different mailboxes to store deleted mail if I keep the special_use lines?

special_use is independent of the autoexpunge. I guess it wouldn't necessarily hurt.. but it's also somewhat better to have only a single \Trash mailbox so clients don't become confused when more than one of those mailboxes exist.

Got it.

Thanks, Timo.
