Very odd. It might be the same software, but what I am seeing is the bouncer doing:
1) Copies the original headers minus Received trace headers, 2) Change From: to the mailer daemon address 3) Change To: to the return path address 3) Adds headers for DSN mime parts. The only reason I am seeing this because we are signing mail now and I'm seeing the new invalid signature logging with these type of bounces. -- HLS Hector Santos wrote: > Sonneveld, Rolf wrote: >> On 04-10-10, *Hector Santos *<hsan...@isdg.net> wrote: >>> I am wondering or under what scenario would a DSN (bounce) agent keep >>> the original signature in its bounce notification 5322 headers? >>> >>> It was a legitimate bounce for a non-delivery address.� But it kept >>> several headers from the original message in the DSN message headers: >>> >>> ��� DKIM-Signature: >>> ��� Organization: >>> ��� X-Mailer: >>> >>> What logic is there to this? >> RFC 3462, chapter 2. >> >> <quote> >> >> �� The Text/RFC822-Headers body part should contain all the RFC822 >> <http://tools.ietf.org/html/rfc822> >> �� header lines from the message which caused the report.� The RFC822 >> <http://tools.ietf.org/html/rfc822> >> �� headers include all lines prior to the blank line in the message. >> �� They include the MIME-Version and MIME Content-Headers. >> </quote> >> >> /rolf > > The report does contain the original message.
