Microsoft will enforce Sender ID:
Now Microsoft apparently wants to enforce the system on its own, because soon all emails to Hotmail users that do not come with Sender ID will be visibly marked for Hotmail users and thus labeled as potential spam.
Great. Very big strategy. The working group was dissolved because no agreement could be reached because the patent situation with Sender ID was not resolved by Microsoft - and now Microsoft simply wants to enforce it again.
But I think that in this case Microsoft is cutting into its own flesh: there have long been significantly better webmail services that also play significantly better in the network community. Hotmail has long since lost the importance it once had before being sold to Microsoft. Therefore, my prognosis is that not many people will be particularly impressed by this step. The victims are the Hotmail users and possibly their correspondents, who are stuck with an even inferior mail service anyway ...
