I have a Postfix server running with also Postgrey enabled. It seems

that everyone and their mother is spamming my postmaster account. I
don't know if the message filters and greylisting I have configured on
the server are being applied to mail sent to postmaster because very
obvious spam that my smtpd_*_restrictions under main.cf should be
filtering and then if not, Postgrey should for sure be filtering them
out!
I am just trying to understand why this spam is getting through.
Some older versions of postfix give special treatment to the
postmaster address. To disable this special treatment, add
# main.cf
address_verify_sender = $double_bounce_sender
