A recent poster asked for configuration to be checked, and it has made
me question my own sender and recipient restrictions:
smtpd_sender_restrictions =
permit_sasl_authenticated,
permit_mynetworks,
check_sender_access hash:/usr/pkg/etc/postfix/sender_access,
reject_non_fqdn_sender,
reject_unknown_sender_domain,
reject_unknown_address,
permit
smtpd_recipient_restrictions =
permit_sasl_authenticated,
permit_mynetworks,
reject_unauth_destination,
check_sender_access hash:/usr/pkg/etc/postfix/sender_access,
reject_unauth_pipelining,
reject_non_fqdn_recipient,
reject_unknown_recipient_domain,
reject_rbl_client zen.spamhaus.org,
check_policy_service inet:127.0.0.1:10023,
permit
Having looked at my recipient restrictions, I see that I am checking
my sender_access again. Is this right?
Should I replace this with:
check_recipient_access hash:/usr/pkg/etc/postfix/recipient_access
And create a file listing valid users who can receive mail? I have
read postconf(5) and I that is my understanding.
Any thoughts?
