Solution to SMTP / Transport Authentication

[san jan]

For sending mails if you have Authentication problems, probably
one of the below settings may be untouched.
1) setting "mail.smtp.auth" property to "true"
2) using Session.getDefaultInstance(props, myauth)--where myauth is javax.mail.Authenticator instance.
3) using transport.sendMessage(..) instead of transport.send()

I didnot check for authentication while connecting --transport.connect(host,username,password).
Instead i tried authenticating while getting session -- step 2 above and transport.connect(). Even that should work.
