IMHO, the Delivered-To: mechanism has to be deactivateable.
I removed those lines from source, because we are not able
to use postfix anymore if not.
We are using very complex procmail-filters for our support
and other nonsingle-user accounts.
E.g. mail reaches support, it'll be bounced to some user
and if this user is on vacation, it'll be bounced back and postfix
does not like this... :-(
