Some mail clients make space between ":" and "<" (with normal sequence HELO before).

Maybe You thought about some option to don't accept messages "MAIL FROM:<>"?
1446    if (len == 0) /* MAIL FROM:<> -- error message ? */
1447      return 0;   /* We accept it, sigh.. */

Here "-1" and next nice option for spammers :-)

BTW, someone should think up SMTPng with better antispam mechanism.
