I don't reject invalid HELO's or invalid rDNS and get very Little
spam, because I just ban all those shitty TLDs.
I have found out that most spam uses those new shitty TLDs so just
banning these shitty TLDs in the MIME from and MAIL from is a good

MAIL from stage:

    message = Banned TLD
    sender_domains =

then one for Mime from stage:

    message = Banned TLD in MIME From ($h_from:)
    condition = ${if match

That solves most current spam problems.
