Using SPF on your domains…

It’s a good idea if you have a domain – and you have access to your DNS server, that you setup and use (properly) SPF records.  SPF = Sender Policy Framework.  This is an an e-mail validation system designed to prevent e-mail spam by addressing a common vulnerability, source address spoofing.  Here at Amixa, we use SPF records on all of our domains that send email, just to add another layer of anti-spam protection for our clients.

In recent weeks we’ve noticed a sharp increase in spoofed “from” email addresses attached to bulk email sent by spammers.  The “Amixa Sales” email address has been spoofed by some senders and any receipient’s ISP that uses SPF lookups, are properly rejecting the spam messages because the email messages do not originate from our email server.  I am sure other people are getting spam emails using our forged email address, but that is just the way things happen on the internet.  Some people are good, and others aren’t!
