I was trying to configure Mail server setup following the link "

Unfortunately, there isn't enough information in the server.log to troubleshoot this issue.

Please do the following:
1) Add the following property in the ejb-jar.xml so that addtiional debug logging is added for the Mail-Poller.

<activation-config-property>
<activation-config-property-name>debug</activation-config-property-name>
<activation-config-property-value>true</activation-config-property-value>
</activation-config-property>

2) Add the following properties to the appian_log4j.properties file under <APPIAN_HOME>\\ear\\suite.ear\\resources
-> log4j.logger.com.appiancorp.messaging.MessagePublisherServiceImpl=DEBUG
-> log4j.logger.com.appiancorp.mdb.EmailHandlerBean=DEBUG

3) Disable Partial Fetch (for performance improvements)
<activation-config-property>
<activation-config-property-name>partialFetch</activation-config-property-name>
<activation-config-property-value>false</activation-config-property-value>
</activation-config-property>

4) Reduce the interval of polling for the mail-server (From 300 seconds to 60 seconds) temporarily, so that the mailbox is polled every minute (for the sake of TESTING only)
<activation-config-property>
<!-- polling interval in milliseconds
                    the setting provided below is every 1 minute
                    consult your mail admin for acceptable frequecy -->
<activation-config-property-name>pollingInterval</activation-config-property-name>
<activation-config-property-value>60000</activation-config-property-value>
</activation-config-property>

This way, you dont have to wait 5 minutes for the mail-poller to poll your mailbox.

5) Clear out the server.log and send me a new copy of the server.log so that I can review it.
