The RFC clearly states that your should name the postmaster address
world-acceptable *OR* give an alternative email address insead. I think it
is okay to let your blocked users contact you on your gmail addy instead..
:P
My mail server at my pc tells you to mail to
blacklist-{DailyRandomCode}@{domain.dom}...

I would simply look at the dns record, domain record and website instead...
