SPF and Sender ID

Recent reports on slashdot et al seemed to suggest that Microsoft’s Sender ID initiative was dead in the water as it had been rejected by MARID. It seems however that this was perhaps not so accurate.

I have only recently found out about SPF (Sender Policy Framework) and it sounds great. I run a number of servers for clients and I know how much spam is flying around out there and how hard it can be to filter it out. If SPF can limit the amount of spam that is coming from spoofed addresses I think this will be an enormous breakthrough. On the surface at least, it should force spammers to use their own machines to send out their noxious effluent. That should make it easier to block them.

In theory anyway.

In the next few weeks I’m planning on getting SPF and postfix working together and relaying some domains through it to see how it works. Fingers crossed.
