I used Lazyexpunge.
I tried to create .DELETED without any hints and see that the creation was successful. I want to prevent users from creating .DELETED, what should I do? My settings > plugin { > lazy_expunge = .DELETED/ > } > # > > namespace { > prefix = .DELETED/ > hidden = yes > list = no > separator = / > location = maildir:/var/vmail/backup/expunged/%d/%n > }
