A Don't you think you guys are telling that what is SPF and how should we use it. SPF is in system for a while, almost everyone is aware what it is. And what it does. funny enough, no one answered to the actual question. all this info is available on the web. Anyways Prabh S.

Can you tell me how to set reject action? Fix your backup server to have the data required to perform the filtering. Don't force the rest of the world to waste cycles and bandwidth attempting to send email to a backup MX that you have advertised. If you can't do it correctly, DO NOT DO IT. > Prabh S.

Reject Action For SPF
Dear Friends, i have setup SPF alright, postfix is performing check as well (results below), but even if there is no SPF record exist for a domain, message is still accepted. how can i set the reject action, if no SPF available. May 3 16:11:14 titan postfix/policy-spf[5353]: : SPF none (No applicable sender policy available): Envelope-from: somedomain.com Prabh S. Mavi Prabh S.
