Okay, so how many of you have implemented SPF in *your* DNS? And how many of you are actually able to use SPF as a valid check in your current filtering? What are you using to check SPF?
My understanding of SPF is, you could use it as part of your spam filtering process under the following conditions... please correct me if I'm wrong: 1. You have to have the software to support it (iMail does not have the ability to check SPF records for inbound mail) 2. The rule is basically, "if the FROM address domain does NOT have an SPF record, stop the SPF checking right there and do nothing to the message. If an SPF record DOES exist, trust its contents: If the FROM domain does not line up with the list of servers authorized to send on behalf of that domain, it's safe to reject the message". Someone once published a location where a "tool" was provided, making generation of SPF records "easier" by asking you all the questions and then creating the record. Can someone point me to that location again? Sorry if I've posed these questions in the wrong way, or have a complete misunderstanding of SPF... it's still new to me... I just know there was some sort of "deadline" for creating SPF records in your DNS, and we haven't done it yet... so I'm trying to get started on it ASAP.
