Hotmail saga due to spam-filtering?
Yahoo News UK is carrying a story on disappearing messages sent to Hotmail accounts by Apple Mail users.
The article points out that the problem is not restricted to Apple Mail. Customers of several ISPs including Comcast, Rogers and Cogeco are experiencing similar disappearances.
The problem may be due to an overzealous use of spam-filters on Microsoft’s part. Whatever the cause, it seems that no resolution to the problem is in sight.

I just tested sending a message to my hotmail (”spam honey pot”) account and it arrived just fine (well, in the “Junk” folder) even with no priority changes.
Since I can’t test this myself, here is something to test - my guess is that hotmail is looking for the X-Priority header for some reason - sending messages as “Normal” priority does not add this header in Mail (which is smart). However, you can add this header to all your outgoing messages typing the following in the Terminal (with Mail closed):
defaults write com.apple.mail UserHeaders ‘{”X-Priority”=”3″;}’
This will add a X-Priority header to ALL outgoing messages, “3″ represents “normal”. I don’t know whether this works (since I can’t get messages not to arrive to my account) by my guess is it should - if you normally don’t use priorities you should be fine (I don’t know what happens if you set another priority from the UI).
In order to reset this, you would type the following in Terminal:
defaults delete com.apple.mail UserHeaders
