Sorry I missed the original post
change your eq $sender_helo_name to:
{match{${lc:$sender_helo_name}}{slett.net}} and if you have more
than one domain you are handling change the slett net to an
expansion (file, lsearch, named list, etc) that contains the
domains you want to test for. The matches statement would match
on evil.slett.net, me.slett.net, etc
