The "Debug: expunge" is written by doveadm, because you gave it a -D parameter. It tells what messages it's about to expunge. The "Info: expunge" is written by mail_log plugin when anything gets expunged. > 1.A. > Would not it be faster not to enumerate for large mailboxes (30-40GB - > Maildir)?

The default is to expunge only a single user. And why do you mention maildir if you're using mdbox? In any case the size of the mailbox is rather irrelevant. Number of messages is more relevant. > 2. > Also. expunge does not appear to remove empty mailboxes, is this a bug > or intentional? If intentional, why? Any way to automated removal of > empty mailboxes? Well, for your situation when removing mails from .EXPUNGED/ it makes sense, but for anything else it definitely shouldn't be automatically deleting any mailboxes. Maybe there could be an option to do this, although it's a bit problematic if doveadm expunge is being run at the same time as user is expunging more messages. It shouldn't delete mailbox if new messages just got added there. (And that probably isn't very easy to implement.)
