SYMPTOMS
========

If you attempt to send a message through the Microsoft Mail Gateway to X.400 to
a foreign system on which the message transfer agent (MTA) is configured for a
checkpoint size of 10, the message may not be sent successfully, and the
following error message may be displayed:

If you attempt to send another message through the Microsoft Mail Gateway to
X.400 after the above error message is displayed, you are unable to do so. Note
that this problem only occurs if you attempt to send the message using Transport
Class 4 (TP4). The problem does not occur if you send the message using
Transport Class 0 (TP0).
