Maybe using Batch SMTP, or UUCP, or some other scheme which is
designed to preserve the envelope would be better than using
aliases and POP?

Well, aliasing and forwarding is simple redirection. No headers
are added.
From various mail RFCs we can understand that there is no
connection between headers in the e-mail message and envelope
(sender or recipient). Which means that by just looking at the
headers you have no way to know whom the message was addressed
to. Many MTAs add the Envelope-To: header, but I don't think
there is any other way to get the envelope recipient.

Probably not a good idea anyway. Resent- headers are not for
this.

What if there already are several groups of Resent- headers in
the message? And your aliasfile director redirects the message
several times? Which group of Resent- headers is the correct
one?
