The following accept rule should be removed, it makes the rest of the
local domains rules not that useful... and there is already a rule to
accept mail fro local_domains (as long as some other tests match). ACLs
are checked in the order they appear.

This one is probably the culprit as you tell Exim to accept any mail if it
can verify the helo string.

>   accept  verify                = helo
