No matter what, you will still get a massive amount of hits on 21, 22, 23, 25, etc., which are just script-kiddies trying to find an open server.  Ultimately, ignore.  If you get one that just hounds your board day in a day out, put an IP range block on the source.  Mine usually come from China, Vietnam, Brazil, and occassionally, Russia.
