The information in this article applies to:

- Microsoft Mail Gateway to SMTP, versions 2.1, 3.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

Versions 2.1 and 3.0 of Microsoft Mail Gateway to SMTP may display this error
message:

  "ERROR write: (1) (null)"

This error message indicates that the SMTP Gateway was unable to send packets to
the SMTP router configured in the Admin program. It should be configured in this
manner:

Gateway-SMTP-SETUP:

  IP address of SMTP Router

CAUSE
=====

This error message may appear if:

- The SMTP router goes down.

- The network between the SMTP gateway computer and the SMTP router is down.

- A problem occurs in the TCP/IP on the gateway computer.

RESOLUTION
==========

You can test these trouble points by trying to "telnet" to port 25 of the
smarthost. Once this test is successful, the gateway will run. Send the message
again. If the error occurs frequently, check the network with a protocol
analyzer for problems.
