JavaxMail JNDI properties: mail.smtp.user vs username

Question

What's the difference between mail.smtp.user and username? Are either where I specify the destination address (to field)? If not, what property does the destination address correspond to?

Answer 1

Hope this helps:

• mail.smtp.user property can be set to provide a default username for the callback
• username and password are used during the Call the Transport connect method explicitly
