Yes. Although Microsoft has refused to disclose what they have actually applied for patents on, their license only applies to specific parts of Sender-ID, which seems to imply that they did not apply for patents on SPF itself. In any case, it is certainly seems safe to continue using SPF for now.

More like "Who needs patent problems?"

The position appears to be 100% on patents and licencing, not on the technology or the concept.

Next question: presumably SPF, though now a subset of Sender-Id, is still unencumbered, and thus usable in SA 3.0?
