Actually, you also have to set the smtps properties when using smtps.

Simply set the mail properties to include:

mail.smtps.host
mail.smtps.auth

You're trying to send mail over a connection that expects an encrypted connection (TLS in this case).

This sun forum has several solutions that you might try: http://forums.sun.com/thread.jspa?threadID=617974

He is, but he's also given the javamail property that should promote the connection to TLS after connecting. – Geoff Apr 29 '10 at 18:03

For javamail to GMail SMTP I use the following properties:

mail.smtp.host="smtp.gmail.com"
mail.smtp.port="587"
mail.smtp.auth="true"
mail.smtp.starttls.enable="true"

I wasn't aware that GMail accepted mail on port 25. Perhaps that is the source of your problem.

Obviously you still need to perform authentication, usually via mail.smtp.user and mail.smtp.password .

by changing the port I got this error com.sun.mail.smtp.SMTPSendFailedException: 530-5.5.1 Authentication Required. Learn more at 530 5.5.1 http://mail.google.com/support/bin/answer.py?answer=14257 i35sm2744098gve.26 – user327136 Apr 29 '10 at 18:06
I've ammended my answer, obviously GMail is not an open relay, you do need to perform authentication. – Geoff Apr 29 '10 at 18:08
