Unfortunately, there are many clueless mail admins and/or badly/mis 
configured mail servers out there.

The reality is that the RFCs mandate that the null sender envelope 
address is one that must be accepted, as there are many tthings smtp 
that depend on it.

That said, I really don't care if their server rejects our user 
occasional vacation message or not, so it isn't something I even care 
about knowing about, other than to tell a user that the reason their 
valuable vacation response wasn't received by their VIP customer is 
because their VIP customers genius mail admin decided that they didn't 
want to receive any of those kinds of emails, so go complain to them if 
they want to complain to someone.


Best regards,
