Hello,
I have the following configuration for the recipient restriction:
permit_mynetworks
permit_sasl_authenticated
reject_unauth_destination
reject_non_fqdn_sender
reject_non_fqdn_recipient
reject_unlisted_sender
reject_unlisted_recipient
reject_unknown_sender_domain
reject_invalid_hostname
reject_rbl_client zen.spamhaus.org
reject_rbl_client bl.spamcop.net
check_policy_service inet:127.0.0.1:2501
I would like that sender domain names for which is not configured any MX record
are not relayed from my MTA. I have tried to use the restriction
'reject_unknown_sender_domain' but it does not seems to work or maybe a do not
have understud the right place where to put it. Moreover, I would like to
reject immediately a message that has not an MX defined for the sender domain.
I saw also the restriction 'reject_unverified_sender' that it could be worth.
Could some one explain me better the difference between the two restrictions?
Thank you in advance!
