I have some users where I'd like to expunge their mail at different times.
For example, I may have some users who I want to expunge everything from every folder at 30 days.
Others where I'd like to expunge everything at 90 days.
And still others where I only want to expunge mail from the Trash and Junk folders, and nowhere else.
Is there a way to do some sort of lookup for this? Or is this beyond the ability of the autoexpunge feature? Should I just use a cron job and use "doveadm expunge" on a user-by-user basis?
You can override any mail-related setting from userdb. So for example if you have:
namespace inbox { mailbox Trash { autoexpunge = 30d } }
You can have your userdb return namespace/inbox/Trash/autoexpunge=90d extra field for other users. http://wiki2.dovecot.org/UserDatabase/ExtraFields has some examples.
