Yes, that's the thing, but HELO is accept in that place:

~ :( % telnet xxx.net 25
Trying 89.291.440.279...
Connected to xxx.net.
Escape character is '^]'.
220 xxx.net ESMTP Exim 4.62 Thu, 26 Oct 2006 00:50:01 +0200
HELO xxx.net
250 xxx.net Hello xxx.net [82.230.172.234]

HELO is still allowed. I really would like to deny it here.
