There is a mail header called Return-Path. Here's the relevent RFC section on it:
This field is added by the final transport system that
delivers the message to its recipient. The field is intended
to contain definitive information about the address and route
back to the message's originator.
Note: The "Reply-To" field is added by the originator and
serves to direct replies, whereas the "Return-Path"
field is used to identify a path back to the origina-
While the syntax indicates that a route specification is
optional, every attempt should be made to provide that infor-
mation in this field.
The final transport that delivers the message to the receipient is supposed to attach
this header to the mail message just before delivery. That's all well and good, but if
you're writing a system that you want to deal with bounced messages, that causes a
problem because the most likely Return-Path that a MTA will assign is the From address.
In the case of a list serv, all bounces would be returned to the user that posted the
message rather than to the list manager.
I'm using MIME::Tools to create the message, and Net::SMTP to send it.
I've tried manually setting a Return-Path but the MTA just sticks its own at the top of
My question is, have any of you run into this problem before? Is there a universal way
of forcing a Return-Path? Is there a more appropriate field to use?
