If you are using a Gmail account you should do the following: 

name="mail/MailSession"

auth="Container"

type="javax.mail.Session"

mail.imap.host="localhost"

mail.pop.host="localhost"

mail.store.protocol="imap"

mail.transport.protocol="smtp"

mail.smtp.host="smtp.gmail.com"

mail.smtp.port="465"

mail.smtp.auth="true"

mail.smtp.starttls.enable="true"

mail.smtp.user="username"

password="*****"

mail.smtp.socketFactory.class="javax.net.ssl.SSLSocketFactory"

/>
