Thanks for the info. So is info message showing the wrong mailbox or is it deleting from the wrong mailbox? I did specify mailbox ".EXPUNGED/*".

Let me rephrase that. Some users are using maildir. and more than one of such users with 30-40Gb of emails, approx 100-800k/message. approx 85899345 messages. 20-50 mailboxes under each user. And messages get deleted often. When expunging, lazy expunged, messages from such mailboxes, individually at separate time. Would not it be faster/safer reading from expire database compare to enumerate everything? I was hoping to setup a script to expunge, lazy expunged, messages from each user, at diff intervals, based predetermined rate of delete. > >> 2. >> Also. expunge does not appear to remove empty mailboxes, is this a bug >> or intentional?
