So I wrote check_helofqdn (attached). I haven't finished it (I
need to smarten up the regex that looks for IP addresses, see
section 4.1.1.1). I was thinking of having an optional DNS test to
see if the name given to EHLO was, in fact, a valid A record
(instead of just testing for the presence of at least one dot in
the name), using the same sort of framework that the dnsbl code uses.
In the past I found it (or something similar) to give too many false
positives. Maybe today it's different.
I'd be curious to see what you find.
One variation that might be useful would be to have the plugin just
add a header and then have a spamassassin rule to nudge the score a
bit...
