Our HP UX program executes "elm" commands to generate auto-emails with attachments (using sendmail). Each outbound email will utilize a customized "From:" address. The outbound "From:" addresses are changed on this batch job to mask how recipients see that they are coming from their associated contacts on site. Th HP UX is relaying through the other Exchange server. This works fine.
However, the problem is that "undeliverables" are sent back using the "Return-Path:" of the submitter. I need the "undeliverables" to go to the respective "From:" address on the original outbound message.
Sendmail derives return path of the submitter unix login@localhost.com. I think the solution lies in changing the "Format of headers" parameters in the sendmail.cf. Or possibly "FEATURE(masquerade_envelope)". I am sendmail novice and have not touched this before. Any help will be appreciated.
