smtpd_recipient_restrictions = permit_mynetworks,
reject_unauth_destination,
check_policy_service unix:private/policy,
reject_unknown_recipient_domain,
reject_invalid_hostname,
reject_non_fqdn_sender,
reject_non_fqdn_recipient,
reject_unknown_sender_domain,
reject_unauth_pipelining,
smtpd_helo_restrictions = permit_mynetworks,
reject_invalid_helo_hostname,
reject_unknown_helo_hostname,
reject_non_fqdn_helo_hostname
smtpd_recipient_restrictions = permit_mynetworks,
reject_unauth_destination,
reject_non_fqdn_recipient,
reject_unknown_recipient_domain
