SPF

Finally, an idea I’ve had years ago seems to have occurred to others, too… namely, cutting down on spam e-mail by verifying that the originating server is a valid server for the sender’s domain. The mechanism developed for this purpose is called SPF, or Sender Policy Framework. I just set up my domains with SPF records… let’s see what happens! Of course SPF is not going to do the trick until a number of major providers begin to adopt it, but the fact that gmail has done so is quite encouraging.
