My server should have to reject the message, whereas - as you can see - it is
accepted and sent to the destination mail host. I think that there is a trouble
in my my recipient restriction configuration:
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
Maybe should I put:
reject_unknown_sender_domain
before:
permit_sasl_authenticated
?
And if so, is there an way to do so all messages in deferred queue will be
reject in they have not a valid sender domain?
