SYMPTOMS
========

When you send an e-mail message from MSN, The Microsoft Network, to an
Internet address, the recipient may receive the message multiple times.

CAUSE
=====

When MSN sends an e-mail message, SMTP verifies the connection, sends the
body of the message, and then waits 90 seconds for verification that the
message has been received. If no confirmation is received, MSN assumes
that the transmission has not been completed and sends the message again.

Occasionally, the necessary confirmation is not received within 90 seconds
due to slow processing on the receiving server or unusually noisy
telephone line conditions. If MSN does not receive the necessary
confirmation within 90 seconds, the message is repeatedly sent until
confirmation is received. In these cases, the recipient receives the
message multiple times.
