Very similar checks, probably not the same exactly.. I have not done any 
comparison.. See `grep HELO /usr/share/spamassassin/*` to see what they 
check..


If so will we run into the

It may be tagged as spam and whatever you configure MailScanner to do - 
it will do. That's easy to deal with though. You can whitelist by IP, or 
change the scores of the HELO rules, or write new rules to offset the 
HELO rules.
ie: look for
HELO =~ /(?:somecompany|someothercompany)/ (not tested)..
