I'm running ONMS 1.5.90 on Red Hat 5 and trying to get the Mail Transport Monitor to work in my environment. My first goal is to initiate the test sending mail message to go from my ONMS server to my separate email server (which properly sends out all my notifications via email and text messaging) to it's destination of a gmail account.

Following the documentation from the ONMS website, I've edited the javamail-configuration.properties, capsd-configuration, and poller-configuration.xml files. And added a modified the mail-transport-test.xml file I located in /opt/opennms/examples

Upon restart of ONMS, within the WebUI, I do see the new "MAIL" service added to only the separate email server (not every server that we have SMTP port 25 running), but it show's the "MAIL" service as down with the reason code: Exception from mailer: null

I do see in the poller.log file

Below are my javamail-configuration.properties, capsd-configuration, mail-transport-test.xml, and poller-configuration.xml files edits or additions.

The existing javamail-configuration.properties.xml file with sending out notifications to our external email server. This works fine for sending out notifications:

added to capsd-configuration.xml

<!-- Quick and dirty to set up the MAIL service on an interface -->
<protocol-plugin protocol="MAIL" class-name="org.opennms.netmgt.capsd.plugins.SmtpPlugin" scan="off" user-defined="false">

<property key="retry" value="2" />
<protocol-configuration scan="on" user-defined="false">

added the mail-transport-test.xml file

<!-- These 2 properties are passed directly to the javamailer class. The will

<javamail-property name="mail.smtp.userset" value="false"/>
<javamail-property name="mail.smtp.ehlo" value="true"/>

<!-- Connect to local MTA and send... no auth required but the configuration

<sendmail-host host="192.xxx.xx.xxx" port="25"/>
