Are you configuring the smtp server to be secured? Is it using SSL anywhere? That could be an issue.

Thanks for response Bart Simpson, As your suggestion I have unchecked use secure network connection in control panel. Now I am not getting the above exception. my code exicuting without exception.

But I am not able get a mail to as I have set in my code. Please can you have a look on my code, is because of unchecking secure network connection or code issue ,mail is not getting?

It happens because of server has self signed certificate. To resolve issue you can add this certificate to the list of trusted certificates of your JVM. Check below URL for procedures to add certificates in JVM.

I agree for your point manish, I was succeded to send create account notification to user by setting smtp server details in control panel before. For that I have not configured any ssl security that time.

My question here is , Is we need to compulsarly follow ssl security to send a mail from liferay custom portlet? Why not needed any ssl configuration to get mail for account created notification? what is the difference here.

Please double check if there is a firewall that blocks the smtp.
I use Avast that causes this issue.
