Great!  Thank you :-)

Just a couple questions:

1) Will MailScanner use them as the source of information? or just
write them on output?

2) Is there any way to guarantee the ordering of the headers?

For example, if they're in the source in a particular order (as I put
the other messages, for CommuniGate Pro, Envelope-To has to be first,
and then Return-Path), is it guaranteed that MailScanner will keep them
in that order?

Or, if MailScanner is only generating them, and not reading them from
the input, is there a way to make sure MailScanner puts them at the top
of the message?
