There is a better option.
Since the  python.org folks run  exim 3.21, they  could stick this  in their
exim.conf:
----------------------------------------------------------------------------
sender_verify_hosts_callback = /etc/mail/badsendinghosts:*
sender_verify_callback_domains = /etc/mail/baddomains:*
# Wait up to 90s for the remote mail server to answer
sender_verify_callback_timeout = 90s

# Refuse messages with bad headers
headers_sender_verify = true
headers_check_syntax = true
headers_checks_fail = true
----------------------------------------------------------------------------

The first 4 lines refuse any mail that  can't be replied to, and gets rid of
a lot of  spam (most of it  actually), the other ones catch  other mail that
doesn't look right.

See the exim.org documentation for more info on those.
