$sender_address to be correct, I think.

$sender_helo_name

Recently there was some thread about this on the list, maybe
http://www.exim.org/pipermail/exim-users/Week-of-Mon-20030901/thread.html#58944
and e.g.
http://www.exim.org/pipermail/exim-users/Week-of-Mon-20030901/058972.html
could be of any help to you.

Quick example:

deny condition = ${if match {$sender_helo_name}{(mailin-04.mx.aol.com|\
<other-helos-to-match>)}{yes}{no}}
     message = rejected: I don't like your helo


Or use "eq" instead of "match", if it should be equal.
