hello
I've arrived at this thread a bit late.

My domain accepts mail from <>. Just not for postmaster. We never send out mail from <[EMAIL PROTECTED]>; there's no reason to expect a DSN for that address.
I defy anyone to show me an RFC that says an SMTP implementation MUST accept mail from <> to <[EMAIL PROTECTED]>
I had a problem recently where email with a return receipt request set arrived here. sendmail duly acknowledged that request. However the mail server at the other end rejected the receipt notification. I spoke to the network admin there and explained that as far as I know you need to accept an envelope sender of <> for exactly the circumstances of return receipts and so on. I found section 6.1 of http://www.ietf.org/rfc/rfc3461.txt?number=3461 and partly related was section 5.3.3 of http://www.ietf.org/rfc/rfc1123.txt?number=1123 Seemed to confirm my thoughts.
have I handed out incorrect advice to someone in respect of the envelope <> address?
regards
rolf.
