[exim] reject mail with fake from

Hi,

I received some spam with a @meleeweb.net and valid $local_part (user
exist). but they came from host not in relay_from_hosts. And I would
like to nuke them

I wrote these ACL :

acl_check_rcpt:

...

accept authenticated = *

  accept  local_parts   = postmaster
          domains       = +local_domains

  require verify        = sender

  deny    message       = You can't send message with this From: header
          domains       = +local_domains
          sender_domains = +local_domains

  accept  domains       = +local_domains
          endpass
          verify        = recipient

  accept  hosts         = +relay_from_hosts

  deny    message       = relay not permitted

I would like to known if this is correct and/or reliable ?

Thanks
