All - thanks for the replies, here are the answers if I missed anything
please let me know!

The SendMailServlet is in the examples, that should be mapped correctly by
default, right?

The web.xml in webapps/examples/WEB-INF is the defualt.  I was assuming
since it came with the examples all would be good as the other servlets are
running fine...

The logs do not seem to tell me a lot.   Any suggestions?

The mail server is running on the local machine.

The From address is valid.

My firewall doesn't appear to be an issue as I have tested with it enabled
and disabled.

Here is my ResourceParams for the mail/Session for localhost:

         <ResourceParams name="jdbc/EmployeeAppDb">
            <parameter><name>user</name><value>sa</value></parameter>
            <parameter><name>password</name><value></value></parameter>
            <parameter><name>driverClassName</name>
              <value>org.hsql.jdbcDriver</value></parameter>
            <parameter><name>driverName</name>
              <value>jdbc:HypersonicSQL:database</value></parameter>
          </ResourceParams>
          <Resource name="mail/Session" auth="Container"
                    type="javax.mail.Session"/>
          <ResourceParams name="mail/Session">
            <parameter>
              <name>mail.ctg.com</name>
              <value>localhost</value>
            </parameter>
          </ResourceParams>
          <ResourceLink name="linkToGlobalResource"
                    global="simpleValue"
                    type="java.lang.Integer"/>
        </Context>

Thanks much!
Chris
