In that case you MUST stop what you are doing immediately, leave the
multi-drop support in place, and make sure that revived messages are
delivered to X-Original-To: recipients and NEVER to the header To/Cc
recipients. It is critical to understand the difference between the
message envelope envelope and message headers when routing mail.
Consider what happens when you revive a stored mail with
"" in the "To:" or "Cc:" line. Consider loss
of mail to "Bcc:" recipients, ...
The Postfix 2.x feature you are trying to turn off is specifically
designed to support multi-drop mailboxes, use it, or rethink how
your mail is processed.
