Hi Viktor
Under acl_check_rcpt acl
I added the following for my ACL (got this off the Exim Wiki - Works like a bomb)
## Forged HELOs
deny message = HELO/EHLO required by SMTP RFC
condition = ${if eq{$sender_helo_name}{}{yes}{no}}
drop message = "REJECTED - Bad HELO - IP address not allowed [$sender_helo_name]"
condition = ${if isip {$sender_helo_name}}
Also you may want to look @ the spam filtering section on the Wiki, These some kewl ideas etc.
HTH
