Hi Jennifer
Try turning debugging on.
In JBoss, you do this by modifying the log4j.xml in \Adobe\LiveCycle\jboss\server\all\conf
Change the threshold from INFO to DEBUG for the file appender, as shown below:
This will cause the EmailReceiver (as well as a whole lot of other classes) to send debug output to the log file:
\Adobe\LiveCycle\jboss\server\all\log\server.log
You should see some lines in the log file each time the EmailReceiver fires. These should tell you what it's searching for, and might give some insight into what's going wrong.
