It's a bad idea to put it into the file when you don't know if the MTA
will remove it.  With MTA's that support Envelope-From (such as
Communigate Pro), it will take the leading Envelope-From headers and
remove them.  Their presence is for communicating between MailScanner
(or any other message submission agent) and the MTA.

It's exactly like the R(PFD) lines in the sendmail qf file, except
everything is in one file.  The MTA gets its RPFD type data from the
Envelope-To headers, removes them from the actual message, and then
proceeds.


When you know that the MTA will do the right thing, it's not "a bad
idea".  And for some MTA's, it's definitely "the right idea".
