[Dovecot] Migrate from Maildir to mdbox

[Henrique Fernandes]

Yeah, i guess the right ocmando would be dsync

dsync get the user from mysql, with user query. I guess.

Are you looking to do it without any downtime ?


Are you getting the mail_location from mysql or in conf file ?

I would use dsync backup. I had some trouble using mirror when a box was
corrupted, it messed up both sides.
