Note: doveadm backup is not a solution because it replicates the current state of the mailstore, what I need is a separate backup that is not altered by user’s screwing things up or accidentally deleting mail. Certainly, a way to expire older mails from the backup would be great, but the crucial “feature” is that the backup doesn’t delete any mails based on user action. -- And I was grounded while you filled the skies I was dumbfounded by truth; you cut through lies
