Good point. It does count towards quota. Worth mentioning also in the setting docs. The mail isn't really "deleted" from the IMAP point of view, it simply gets added that $POP3Deleted flag, so "undelete" is simply removing that flag with IMAP protocol.

Also if wanted this could be combined with cronjob scripts and such to delete old mails, e.g.:

doveadm expunge -A savedsince 1week keyword $POP3Deleted
