18 permit_mynetworks,
19 permit_sasl_authenticated,
20 reject_non_fqdn_hostname,
21 reject_non_fqdn_sender,
22 reject_non_fqdn_recipient,
23 reject_invalid_hostname,
24 reject_unknown_sender_domain,
25 reject_unknown_recipient_domain,
26 permit_mx_backup,
27 reject_unauth_pipelining,
28 reject_unauth_destination,
29 check_relay_domains,
