   Available evidence supports that... I've been running CSV on input for
years. Of 5 million recent email sessions on one server, I found 148 CSA
entries, of which only 6 from cheetahmail.com indicated CSV authorization
for the IP address connecting to us.

   For research purposes I list the "not-authorized" HELO domains:

123mail.org
2-mail.com
airpost.net
bestmail.us
cluemail.com
collaborations.com
elitemail.org
eml.cc
f-m.fm
fast-email.com
fastem.com
fastmail.cn
fastmail.co.uk
fastmail.fm
fastmail.net
fastmail.to
fastmail.us
fmgirl.com
imap.cc
letterboxes.org
mail
mailbolt.com
mailc.net
mailforce.net
mailftp.com
mailite.com
mailnew.com
