eliminating unbracketed numeric HELO/EHLO 's

Hi Matti,

I'm noticing an ever increasing number of unresolved (ie not in DNS)
transactions where the spam-kiddies are not using traditional 
alpha-string type hostnames or bracketed IP's in the HELO/EHLO.

Is there a stanza for smtpserver.conf which can eliminate things
in general like the following (from the smtpserver log):

KDlY05060r      HELO
KDlY05060w      250 relay.phys.ualberta.ca Hello

I'd like to be able to deny access altogether to all hosts that
do not present an alpha hostname or [IP], but do present numeric IP 

For bracketed IP's I know it's easily accomplished with a stanza like:

	\[*.*.*.*\]            999 !NO EMAIL ACCEPTED

but how to do it with ie '*.*.*.*' where the wildcard match expands to a
numeric-only unbracketed IP string?

(I'm running 2.99.55)
