I would seriously like to challenge the following statement on that site: "This may cause a problem since some mail servers check the SMTP hostname banner to see if the hostname points to the same mail server. If not, any mail you send may be rejected or handled as spam." Checks like these are not likely to reject any amount of spam at all, but they will definitely block legitimate messages -- more or less all messages hosted by a hosting provider few (if any, of them provide a unique IP address for each hosted domain). Ignore the advice until you see evidence that it's actually causing you problems. (Besides, the advice doesn't even make sense. It's the banner of the SMTP *server* we're talking about. When your server acts as a *client*, how would the receiving server know your banner? Connect back to the connecting client? Connect back to the MX of the sender address?) > exactly what I want except it does not work :( > > master.cf (before) > > smtp inet n - - - - smtpd -o smtpd_proxy_filter=127.0.0.1:10025 > smtps inet n - - - - smtpd -o smtpd_proxy_filter=127.0.0.1:10025 -o > smtpd_tls_wrappermode=yes > submission inet n - - - - smtpd -o smtpd_enforce_tls=yes -o > smtpd_sasl_auth_enable=yes -o > smtpd_client_restrictions=permit_sasl_authenticated,reject > > master.cf (updated trying to do this - i am using real domain names > and ips) > > #smtp inet n - - - - smtpd -o smtpd_proxy_filter=127.0.0.1:10025 > localhost:smtp inet n - - - - smtpd -o smtpd_proxy_filter=127.0.0.1:10025 > ipaddressgateway:smtp inet n - - - - smtpd -o > smtpd_proxy_filter=127.0.0.1:10025 > ipaddress1:smtp inet n - - - - smtpd -o hostname=domain1 -o > smtpd_proxy_filter=127.0.0.1:10025 The name of the parameter is myhostname, not hostname.
