 **WARNING**:  Pursue **HELO** checking at your own peril.  The HELO is fairly unimportant in the grand scheme of SMTP these days, so don't put too much faith in whatever it contains.  Some spam might seem to use a telltale HELO string, but you might be surprised at how many legitimate messages start off with a questionable HELO as well.  Anyway, it's just as easy for a spammer to send a proper HELO than it is to send HELO im.a.spammer, so consider yourself lucky if you're able to stop much spam this way.
