Sorry, do you mean skips CBV for postmaster *recipient*, or mail-from
return path?  I can understand skipping CBV if the recipient is
postmaster, but not the sender.  After all, isn't the point of CBV to
check if the sender is following the spec by providing a valid return
address?

Example: incoming:

  MAIL FROM:  <postmaster @ somedomain.com>

Don't bother to do a CBV here because even if you do call it, the remote
domain hosting somedomain.com must accept POSTMASTER always per
specification RFC 2821 secton 3.6:

Yes, of course.  But what if they don't?  Do you still want to 
accept mail from such an RFC ignorant domain?
