ID: Q194386

The information in this article applies to:

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: 

   DEBUG (T4_SEND): CONNECTION 32: TP_SEND() FAILED: 3
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).
