I wasn't able to find any helo ACL patch, so don't know what it does.

What I do as standard at the moment, is:

1: Refuse an smtp connection if a valid helo/ehlo isn't given;
2: Refuse the connection if I can't do a reverse lookup on the client.

O.k., so I live in a dream world, that's as may be; my ISP who uses Exim
himself allows anything at helo/ehlo time. But what does the patch do
that my ACLs don't do?

Best,

Tony
