roller trunk, tomcat 6 + mail.jar

[Jeffrey Blattman]

using my standard old roller.xml, on tomcat 6, even though the mail 
resource setting is commented out in my roller.xml the roller webapp 
fails to initialize if mail.jar is not present.

also interestingly, after installing mail.jar, the error message 
complains about localhost, not the commented out mail.example.com in 
roller.xml, so i do not think it's a case of tomcat 6 not honoring the 
comments in roller.xml,

/javax.mail.MessagingException: Could not connect to SMTP host: 
localhost, port: 25;
 nested exception is:
       java.net.ConnectException: Connection refused

/
so i wonder is tomcat 6 providing a default mail transport where it 
didn't in 5.x?

thanks.
