Well it's a domain I host, and the IP is my IP address.

Here's the ACL section, I would gladly accept any advice on how to make
it better. I've removed the standard EXIM comments for space.

acl_check_rcpt:

# Accept if the source is local SMTP (i.e. not over TCP/IP). We do this by
# testing for an empty sending host field.

accept hosts = :

  deny    message       = Restricted characters in address
          domains       = +local_domains
          local_parts   = ^[.] : ^.*[@%!/|]



  deny    message       = Restricted characters in address
          domains       = !+local_domains
          local_parts   = ^[./|] : ^.*[@%!] : ^.*/\\.\\./

# Accept mail to postmaster in any local domain, regardless of the source,
# and without verifying the sender.

  accept  local_parts   = postmaster
          domains       = +local_domains


# Deny unless the sender address can be verified.

  require verify        = recipient
  require verify        = sender

   drop    message = Your mail system is listed at $dnslist_domain.  
Good-bye.

  deny    message       = relay not permitted
