 Keith, we were referring (atleast I was) to the fact that they do EXIST 1
 RCPT limits for a NULL return path.  There are plenty of systems that work
 in this mode whether you care to believe that or not.  The conflict you seem
 to forget is that your multi rcpt-to/null return path allowance is a source
 of spam.

No, what *I* said was that since, *in general*, a bounce only has 1 MAIL FROM
to generate RCPT TO's, and there's a lot of idiot mail admins that feel
justified in saying "Since this is true 98% of the time, we will force it
to be true always...."

I will rephrase that to be "Since in 98% of the time there is only one Recipient in a <> message, if the sender has some need/desire to send a multi-recipient <> message, then such sender should create a separate copy for each recipient and thus send them as single-recipient copies". Thus puts the burden of respecting the one-recipient-per-<>-message "rule" where it belongs - on those processes that generate those 2% of the <> Messages by requiring them to make the effort to conform (ie: By sending multiple single-recipient copies).
