Thanks Richard and Marcus, but I still get denyed because of RBL with both
solutions and Marcus' solution also stops mail going out. Perhaps I didn't
give enough of the acl. It's all the standard stuff except for the
dnslists part. FWIW, I also notice that the $dnslist_domain and
$dnslist_text variables are always blank. This is Exim 4.20


#[ global section ]

domainlist local_domains = @ : j3iss.com
domainlist relay_to_domains =
hostlist relay_from_hosts = 127.0.0.1 : 206.54.173.0/24


#[ acl section ]
acl_check_rcpt:

accept hosts = : 206.54.173.0/24

  deny    hosts = /etc/mail/deny_access_list
          log_message = found in deny_access_list
          message = 550 We don't accept mail from spammers.


  deny    local_parts   = ^.*[@%!/|]
  accept  local_parts   = postmaster
          domains       = +local_domains
  require verify        = sender


  accept  hosts         = /etc/mail/allow_access_list
  deny    dnslists      = relays.ordb.org : sbl.spamhaus.org
  deny    message       = rejected because $sender_host_address is in a
black list at $dnslist_domain\n$dnslist_text
  log_message           = found in RBL $dnslist_domain


  accept  domains       = +local_domains
          endpass
          message       = unknown user
          verify        = recipient


  accept  domains       = +relay_to_domains
          endpass
          message       = unrouteable address
          verify        = recipient


  accept  hosts         = +relay_from_hosts
  accept  authenticated = *
  deny    message       = relay not permitted
