Who said a different MAIL FROM is abusive?  What if I have an account at gmail 
and, for convenience, prefer to collect bounces at that mailbox?  Would I need 
a special permission to do so?

What if helo is verified, bounce address is null, but there is a DKIM-Signature 
which is not aligned.  Is that domain abuse too?

Hm...
