You can't use --authuserX since dbmail doesn't support authorization as an other
user than the one logged in. Of course, it's not needed if you provide
read-access through the acls.

So if:

- you provide read-access to your backupuser on all mailboxes
- subscribe your backupuser to all mailboxes in the #Users namespace

this will work just fine if you simply login with the backupuser's credentials.
