Most mailing lists can automatically detect dead accounts using NDN - but your choice to do it manually or chew on the unwanted bytes for eternity. > Additionally, the mail is also stored to a local > mailbox. I know, that means that users could fetch them via > POP3/IMAP/Webmail, but as it is, they prefer getting it forwarded. Just send the email on as if it is new mail rather than using Postfix for forwarding, and then it will appear to come from the final destination host, and NDN will come back to that host rather than being "general backscatter". I dare say the relevant ".forward" file is trivial to create, but one can probably use the Sender Rewriting scheme code out there if ".forward" is too simple for one's liking. But strikes me if you deliver and forward, perhaps that second step doesn't even need SMTP? What are you doing that encourages you to duplicate every email? Sounds like there maybe a bad design decision lurking.
