My interpretation (hopefully just as valid).
ALEX@AUVM is the "real" sender. The reply-to is to let us know this (he could
have just as easily left it off). Create your own BSMTP mail file and send
it class=M to a non-paranoid mailer. Since LISTs are usually config'd to
send minimal headers, the ones that non-paranoid mailers insert to point
out possible impersonations don't make it to the list members.
