GM1118 Watchdog 100 Instruction Manual
Using Microsoft Exchange as an SMTP server
If your facility uses a Microsoft Exchange email server, it can be used by the Watchdog
100 to send Alarm and Warning notification emails if desired. However, the Exchange
server may need to be configured to allow SMTP connections from the unit first, as later
version of Exchange often have SMTP services or basic authentication disabled by
default. If you encounter difficulties in getting your Watchdog 100 to send emails through
your Exchange server, the following notes may be helpful in resolving the problem.
NOTE
These suggestions only apply if you are using your own, physical
Exchange server! Microsoft’s hosted “Office365” service is not
compatible with the Watchdog 100 using firmware versions prior
to v3.0.0, as Office365 requires a StartTLS connection. Firmware
versions 3.0.0 and beyond have support for StartTLS and are
compatible with Office365.
First, since the Watchdog 100 cannot use IMAP or Microsoft’s proprietary MAPI/RPC
Exchange/Outlook protocols to send messages, you will need to enable SMTP by setting
up an “SMTP Send Connector” in the Exchange server. More information on setting up an
SMTP Send Connector in Exchange can be found at this Microsoft TechNet article:

Next: Your Exchange server may also need to be configured to allow messages to be
“relayed” from the monitoring unit. Typically, this will involve turning on the “
Reroute
incoming SMTP mail
” option in the Exchange server’s
Routing
properties, then adding
the Watchdog 100’s IP address as a domain which is permitted to relay mail through the
Exchange server. More information about enabling and configuring SMTP relaying in
Exchange can be found at this Microsoft TechNet article:
http://technet.microsoft.com/en-us/library/dd277329.aspx
The SMTP “AUTH PLAIN” and “AUTH LOGIN” authentication methods (also known as
“Basic Authentication) for logging in to the server are often no longer enabled by default in
Exchange; only Microsoft’s proprietary NTLM authentication method is enabled. The
AUTH LOGIN method which the Watchdog 100 requires can be re-enabled as follows:
1. In the Exchange console under
server configuration
, select
hub transport
.
2. Right-click the client server, and select
properties
.
3. Select the
authentication
tab.
4. Check the
Basic Authentication
checkbox.
5. Uncheck the
Offer Basic only after TLS
checkbox
6. Apply or save these changes, and exit. Note that you may need to restart the
Exchange service after making these changes.
Finally, once you have enabled SMTP, relaying, and the AUTH LOGIN Basic Authentication
method, you may also need to create a user account specifically for the Watchdog 100 to
log into. If you have already created an account prior to enabling the SMTP Send
Connector, or you are trying to use an already-existing account created for another user,
