I don't know if this has anything to do with your problem but it might.

MSN blocks e-mail from rival ISPs

Microsoft's MSN said its e-mail services had blocked some incoming messages
from rival Internet service providers earlier this week, after their
networks were mistakenly banned as sources of junk mail. (oops... ed!)

Microsoft confirmed Friday it had wrongly placed a group of Internet
protocol addresses from AOL Time Warner's RoadRunner broadband service and
EarthLink on its "blocklist" of known spammers whose mail should be barred
from customer in-boxes. 

Once notified of the error by the two ISPs, MSN moved the IP addresses "over
to a safe list immediately," according to a Microsoft spokeswoman. 

MSN and Hotmail use spam-filtering software and services from San
Francisco-based Brightmail, whose techniques focus on the message's content
when filtering spam. Beyond that, MSN's spam-abuse team compiles its own
list of IP addresses that are known to generate unsolicited junk messages,
and it blocks all messages from them. 

"RoadRunner ended up on MSN's spam blacklist, and they weren't certain why,
and neither are we," RoadRunner spokesman Keith Cocozza said. "We're still
working on this with MSN so it doesn't happen again." 

EarthLink spokeswoman Carla Shaw said that there was a brief period over the
weekend when customer e-mail was prevented from reaching MSN accounts, but
the problem was fixed right away. She said that MSN did not say that the
problem was spam related

Hi Everyone, 

Does anybody had any problem to sending messages to MSN.COM? I can send
messages to,,, and others, but since
last week I cannot send any message to, this is bizarre...

Thanks in advance
