From: okie on 17 Jun 2010 15:28 When sendmail talks to a upstream MTA, and that MTA rejects the email based on user unknown, sendmail successfully sends an NDR to our originator Is it possible to include the rejected address in the subject line of that NDR? j

If YOUR sendmail has rejected the message, it's the SENDER's MTA that generates the NDR. Therefore, no, you can't modify it. If your sendmail receives a rejection message, then YOU generate the NDR, and yes, there's some control over what you can say. However, are you certain that the NDR already doesn't identify the rejected address? The modification you're permitted is the inclusion of text from a static file - per an option (unless support for such was recently removed). I don't remember the option name offhand.

If you mean, 'is there a .cf (or .mc) file setting that will do this', the answer is "No." Trying to do this -inside- sendmail, itself, is -messy-. A much simpler way would be to use 'procmail' as the local delivery agent, if you're not doing so already, and then brew up a recipie to recognize *your* (locally-generted) NDR messages, pipe the message through a script that does the rewrite, and then pipe to formail.

Yes this is the case, I am building the NDR because they are telling me User Unknown, and yes the address is already in the body of the message. My question is with out much difficutly can it be placed in the subject line.

This box is a hub, no mail lives here, does what you mean still apply? Thanks for the advice. J |
