Sender Policy Framework

Filed in archive Anti-Spam Tools on April 9, 2008

If you are administrator you must have got spam from your own email address. How does this happen? How do you stop this? If you have Sender Policy Framework published, you can specify that you only send email from certain IP addresses/servers. If any other machines send a email with your domain name you can treat that as spam. To be more specific when your company domain sends a email to Gmail user, you must have also used SPF (Sender Policy Framework) to list addresses of your email servers, when Gmail receives your email Gmail email server will check your domain SPF record if the ip address is not listed then it's treated as a spam email and email is moved to spam folder. If the IP address is listed it's not a spam email. If you want to create your own SPF please use this wizard. If you've got ideas, suggestions, questions or other ways to control spam please let me know, by leaving a comment here.
