6.1.1.4. USING MICROSOFT EXCHANGE AS AN SMTP SERVER
If your facility uses a Microsoft Exchange email server, it can be used by the IMD PDU 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 au-
thentication disabled by default. If you encounter difficulties in getting your IMD PDU 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 IMD
PDU 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 IMD PDU cannot use IMAP or Microsoft’s proprietary MAPI/RPC Exchange/Outlook proto-
cols 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:
http://technet.microsoft.com/en-us/library/aa997285.aspx
Next: Your Exchange server may also need to be c
onfigured 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 IMD PDU’s IP address as a domain which is per-
mitted 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 Authentica-
tion) for logging in to the server are often no longer enabled by default in Exchange; only Microsoft’s pro-
prietary NTLM authentication method is enabled. The AUTH LOGIN method which the IMD PDU 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 IMD PDU to log into. If you have already cre-
ated an account prior to enabling the SMTP Send Connector, or you are trying to use an already-existing
account created for another user, and the IMD PDU still cannot seem to connect to the Exchange server,
the account probably did not properly inherit the new permissions when you enabled them as above. This
tends to happen more often on Exchange servers that have been upgraded since the account(s) you are
trying to use were first created, but can sometimes happen with accounts when new connectors and plug-
ins are added regardless of the Exchange version. Delete the user account, then create a new one for the
monitoring unit to use, and the new account should inherit the SMTP authentication and mail-relaying per-
missions correctly.
If none of the above suggestions succeed in allowing your Vertiv IMD PDU to send mail through your Ex-
change server, then you may need to contact Microsoft’s technical support for further assistance in config-
uring your Exchange server to allow SMTP emails to be sent from a 3rd-party, non-Windows device
through your network.
