Get rid of all email.getMailSession().getProperties() - they are not required and may be polluting the setup.

Then remove the line that sets the port. (email.setSmtpPort(587);)

  • I removed all those email.getMailSession().getProperties() but still getting the error STARTTLS command. Also did setSSL(true) then getting the error class javax.mail.MessagingException:Could not connect to SMTP host: smtp.gmail.com, port: 465; nested exception is: java.net.SocketException: Cannot find the specified class java.security.PrivilegedActionException: java.lang.ClassNotFoundException: com.ibm.websphere.ssl.protocol.SSLSocketFactory – Chetan Sharma Jan 25 '10 at 14:34
