Hello,

when we started sending aggregated reports (as a not so small ISP),
we noticed the real world behavior...

Our aggregated reports
- contain a header "Auto-Submitted: auto-generated"
- contain a header "Precedence: bulk"
- contain a header "X-Auto-Response-Suppress: DR,RN,NRN,OOF,AutoReply"


I only had:
Auto-Submitted: auto-generated
X-Auto-Response-Suppress: DR, OOF, AutoReply

Now I upgraded as per your suggestion.


- are transferred to the MX using RFC 3461 syntax "RCPT TO:<[email protected]> NOTIFY=NEVER"


GREAT!!

Thank you
Ale
