It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. See the FAQ for guidance on how to improve it.

An SPF record depends completely on what you want to allow and block. We're just shooting in the dark if we don't know what you're trying to accomplish with this record.

Edit your question to include what systems you're intending to allow to send mail from your domain, and what their status is in regard to DNS records pointing to them.

That said, you likely do not want -mx, and there's no reason to have a twice.

@spboyf92 The systems that the messages are being sent from is what's relevant. Please edit your question to include that information. – Shane Madden Aug 22 '11 at 17:07

Even if it is from Microsoft, but they have a wizard with explanation for people who want to implement a SPF record. Follow the step-by-step wizard, read carefully and you'll get your valid SPF record.

The wizard is located at http://www.microsoft.com/mscorp/safety/content/technologies/senderid/wizard/
