Larry,
Yesterday morning I emailed an msn/hotmail user. Yesterday evening I received this from the postmaster:

"This is an automatically generated Delivery Status Notification.

THIS IS A WARNING MESSAGE ONLY.

YOU DO NOT NEED TO RESEND YOUR MESSAGE.

Delivery to the following recipients has been delayed."

It then went on to say that delivery would be attempted 'til Sun. Jan. 26.

Don't know if this info helps, but it sounds like you aren't the only one with a problem. Good Luck!
