| Microsoft's Hotmail demands Sender-ID, backlash to follow
...
| Now, Microsoft's Hotmail, which also handles the mail for MSN users, says
| that they will shortly be checking Sender-ID on all mail to Hotmail and
| will show a yellow warning box on all mail that doesn't pass.
...
| Sender-ID, as defined during MARID, could either use the original SPF
| record format, now known as v1, or a new slightly more flexible format
| known as v2. Both due to the patent license and technical issues with
| Sender-ID, SPF development has gone along on its own using v1 records,
| and the vast majority of published SPF records are v1. Nonetheless,
| Hotmail says that they will only check v2 records, and if a domain has
| no record, they'll treat that as a Sender-ID failure and display the
| yellow warning box.
Where did John Levine here about that? Can anyone confirm it?
