[Exim] Exim Bug

I just noticed a bug in Exim 3.16 though minor

the problem is that it attempts to verify all helo's

>>> host in helo_verify? no (!203.199.70.24)
>>> host in helo_accept_junk_hosts? no (option unset)
220 ifutureinc.com ESMTP Sendmail 8.8.5/8.8.4; Thu, 05 Oct 2000 10:44:08
-0400
helo
501 syntactically invalid HELO argument(s)
LOG: rejected HELO from mta8001.in.yahoo.com
[203.199.70.24]: syntactically invalid argument(s): (no argument given)


or

>>> host in helo_verify? no (option unset)
>>> host in helo_accept_junk_hosts? no (option unset)
