MAIL FROM:<postmaster(_at_)domain> means "send bounces to
postmaster(_at_)domain", NOT "no bounce needed".

In regards to a CBV,  a postmaster(_at_)domain is skipped.

a) This is codified in a standard, where, exactly?

b) This provides spammers a easy way out by sending with MAIL 
FROM:<postmaster...'

c) Wander over to www.rfc-ignorant.org and see all the sites that *don't*
properly support 'postmaster', so the assumption that "We won't check it because
we "know" it's operational" is severely b0rked.
