Is there a tool to recover space used by refcount=0 messages in mdbox storage files?

The wiki talks about it but it isn't clear where the tool is. ~ $ doveadm help purge doveadm purge [-u <user>|-A]

doveadm purge -A will purge all 'deleted' mails from all users. doveadm purge -u john.doe@example.com will remove 'deleted' messages from john.doe@example.com's mail location.

Thank-you for that suggestion.

I had a go with that. I used the "doveadm purge -u <user>" syntax. In the case of a system user that works with just a username.

Verily it did do the mdbox "pack" operation I was looking for.

Suggestion point: This information should be easier to find. For example it may be an idea to link it from the Dovecot Wiki page which documents mdbox ("MailboxFormat/dbox", http://wiki.dovecot.org/MailboxFormat/dbox ). (Should I edit the Wiki directly?)

A concern I had was that "doveadm purge" might also be removing messages which had been marked as deleted.

But there is an "expunge" command as well, so perhaps not.

My next step would be to look at the documentation, but searching for "doveadm" in the Dovecot Wiki turns up nothing. (Should I edit the Wiki directly?)
