So, how do you put the two list owners into the "MAIL FROM:" SMTP
command? It's the argument for this command that turns into the
recipient of a DSN (eventually, because this is inserted into the
"Return-Path" header by receiving MTAs that accept the e-mail).
So, it's very possible that your list has more than one owner, but no
external MTA should be sending a DSN to multiple recipients...the
single recipient would be something like "[EMAIL PROTECTED]".
That may then get expanded into two or more addresses locally, but you
would never greylist that sort of e-mail, since it is originating at
127.0.0.1.
Yes, you could have a "Errors-To" header with more than one address,
but doing that and then accepting mail from "<>" to multiple users is
just asking for joe-jobs.
