Keep in mind that you might get a lot of false positives if
you check the HELO parameter.  The RFC is not very strict
about it.  I think it's perfectly RFC-compliant to *not*
use the canonical host name (in the DNS sense) as the HELO
parameter.  This is especially true if you want bounces to
go to a different server, which is legal and happens quite
often.

Best regards
