I'm sure most of the people on this list understand the concept of an
envelope, but many of us simply don't have dedicated internet links. When
you are forced to use dial-up connections, running sendmail (or any other
MTA) to access the envelope is simply not an option.
Yes, but the sendmail where the envelope is being lost can always slip
it back into the header in any of several ways, storing it as something
like "X-Envelope-To:". This makes the whole thing actually doable, at
the cost of a little more complexity at the middle stage, instead of
being impossible, with a failure of workaround that people think is a
solution. If someone could work out the best way to do it with
sendmailV8, then convince Eric Allman to include it in the standard
distribution (or more precisely, it should be included in any
sendmail.{cf,mc} code that involves things like virtual domains, where
the mail is probably going to be split again), then we could stop
having this discussion every month. :-|
