Email verification in grails

Question

I am new with grails and am developing a web application in grails.

In my registration page I am getting the user's email id and I need to send a mail with authentication link.

http://grails.org/plugin/mail

http://grails.org/plugin/email-confirmation

I have referred these pages and many other pages to do this task. But the problem is, my email is not sending.

I have used

Gmail SMTP server address : smtp.gmail.com
Gmail SMTP username : [email protected]
Gmail SMTP password : -my password-
Gmail SMTP port : 465
Gmail SMTP TLS/SSL required : yes

Mail settings are:

grails { 
    mail { 
        host = "smtp.gmail.com" 
        port = 465 
        username = "[email protected]" 
        password = "mypassword" 
        props = [
            "mail.smtp.auth":"true", 
            "mail.smtp.socketFactory.port":"465", 
            "mail.smtp.socketFactory.class": "javax.net.ssl.SSLSocketFactory",
            "mail.smtp.socketFactory.fallback":"false"] 
    } 
} 
grails.mail.default.from="[email protected]"

but at least

sendMail {     
  to "[email protected]"     
  subject "Hello "     
  body 'How are you?' 
}

is not working.

The exception occured is

Error 500: Internal Server Error

Try this it's worked for me. Notice that: Gmail SMTP TLS/SSL required : yes. But you don't put "mail.smtp.starttls.enable": "true"

grails.mail.host="smtp.gmail.com"
grails.mail.port=587
grails.mail.username="yourUsernameHere"
grails.mail.password="yourPwdHere"
grails.mail.from="defaultMailFromHere"
grails.mail.props = ['mail.smtp.auth': "true",
        "mail.smtp.starttls.enable": "true",
        "mail.from":"defaultMailFromHere"]
grails.mail.javaMailProperties = ['mail.smtp.auth': "true",
        "mail.smtp.starttls.enable": "true",
        "mail.from":"defaultMailFromHere"]
