I have autoexpunge working for various special_use mailboxes, but I'd like it to optionally be used for users for their inbox as well. I'd also like to be able to disable autoexpunge for some users for certain directories.

Is it possible to specify an autoexpunge period for the main inbox? And can autoexpunge be turned off via userdb_import?

Here's some detail behind my questions:

I have the following in 15-mailboxes.conf, and all is working great for the autoexpunge feature for the Junk and Trash mailboxes:

namespace inbox { separator = . mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Junk { auto = subscribe special_use = \Junk autoexpunge = 15d } mailbox Trash { auto = subscribe special_use = \Trash autoexpunge = 15d } mailbox Sent { auto = subscribe special_use = \Sent } }

And I can change the autoexpunge field for those mailboxes via userdb_import in a SQL query - that's working great.

But I would like for some users to expire the main inbox and the Sent mailbox, and for others for there to be no expiration.

Imagine a scenario where there are users who get a maximum of 15 days of storage - everything older than that should expire out. Other users are standard email users - their inboxes, personal folders, Sent mail should never expire.

Adding autoexpunge to the main mailbox gives an error:

namespace inbox { separator = . autoexpunge = 999d ... ... }

doveconf: Fatal: Error in configuration file /etc/dovecot/conf.d/15-mailboxes.conf line 48: Unknown setting: autoexpunge

So is there a way to add an autoexpunge setting to the main inbox?

And can I set autoexpunge to 0 via userdb_import to disable autoexpunge for a particular mailbox? That doesn't give any error, but does it properly disable autoexpunge for that mailbox?

Thanks-

Tom
