Kodak has some webspace (possibly a web farm) in 63.240.114.0/23 and have one customer trying to use them to send pictures via this webspace to one of our users. I'm thinking its the reject_unknown_sender_domain restriction that is causing this. Would putting something like: smtpd_recipient_restrictions = reject_unauth_pipelining, reject_non_fqdn_sender, reject_non_fqdn_recipient, >>>>> check_sender_access hash:/etc/postfix/clients.map, <<<<<<<<<<<<<<< reject_unknown_sender_domain, reject_unknown_recipient_domain, Would this allow 63.240.114.0/23 to send mail? Thanks.
