I am in the process of setting up an SPF record, we have full rDNS setup and its related to our domin name (eg rDNS to ip 1.1.1.1 = outmail.ourdomain.com)
Is there any other ways to stop people spamming and spoofing your domain name? eg people are sending mail with [email protected] as the sender. The problem is that loads of mail server just send me spam notification even though the header clearly shows its from a server in japan and nothing to do with our server.
