Ok, I was able to get this worked out.
From a new CVP 4.1 VXML Server build this what I ended up doing.
ALLOW USE OF TOMCAT ADMIN TOOL
1. Copy admin.xml into Tomcat\conf\Catalina\localhost
2. Copy the admin folder in Tomcat\server\webapps
3. Add a new user, with roles of admin and manager to Tomcat\conf\tomcat-users.xml
ADD NEW MAIL SESSION
1. Copy mail.jar and activation.jar Tomcat\common\lib
2. Restart VXML Server
3. Login to Tomcat Admin
http://localhost:7000/admin4. Go to Tomcat Server\Service (Catalina)\Host (localhost)\Context (/CVP)\Resources\Mail Sessions
5. Select create new mail session, under name enter "mail/Session", under mail.smtp.host enter "yourhost.mail.com"
6. Click save, then click commit changes, close Tomcat Admin
7. In the email element of the VXML app, make the JNDI name "Session"
8. Restart VXML Server
9. Deploy app and test, all works.
Thanks for your help.
