Yes, that's the answer I expected, thank you. I am going to use
Return-Path: header for my goals now.
Didn't know though that "From " is an artifact of one specific mailbox
format and therefore not universally available.
I wanted to know whether there's a special FETCH item or something. My
IMAP server uses mboxes so it somehow
seemed natural to be able to fetch the data that is stored with the
mails :)

I need this info to detect DSNs, btw.
