First, since the PDU 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: http://technet.microsoft.com/en-us/library/aa997285.aspx
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 PDU’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 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 PDU 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, and the 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 permissions correctly.
If none of the above suggestions succeed in allowing your Geist PDU to send mail
through your Exchange server, then you may need to contact Microsoft’s technical
support for further assistance in configuring your Exchange server to allow SMTP e-
mails to be sent from a 3rd-party, non-Windows device through your network.
