  Less then 12 hours ago I guessed that Google will offer something along with its friends urlLink Microsoft and urlLink Yahoo! . It was a bit of surprise that there is urlLink SPF initiative . And urlLink Google together with urlLink GMail are urlLink SPF-enabled already.
Time to think about our mail servers. The promise SPF fights email address forgery and makes it easier to identify spams, worms, and viruses hen domain owners designate sending mail servers in DNS, so that SMTP receivers can distinguish legitimate mail from spam by verifying the envelope sender address against client IP before any message data is transmitted. is tempting, especially the last one (possibility to eliminate receiving the e-mail body), which should save us a lot in times of virus floods.
