All MTAs are supposed to write Return-Path before the final delivery.
CommuniGate and Sendmail certainly do. I was unable to find anything
in the specs indicating what should happen if there was already a
Return-Path there (forgery attempt?), but it seems to me that the MTA
should remove the old one (or rename it). I don't know what common
practice is though. The only mailer I've seen that doesn't generate
Return-Path is Qualcomm's Mac MTA--and that may have changed in newer
versions.

I don't believe there's any standard that specifies what to do with a
Return-Path if you are an MUA. Certainly most aren't going to
display it. Eudora can if you tell it to (I have it turned on).
Outlook probably can. I don't think OE lets you change what headers
get displayed.

I'm not sure which upsets me more: that people are so unwilling to accept
responsibility for their own actions, or that they are so eager to regulate
everyone else's.
