public class SMTPAuthenticator extends Authenticator

        return new PasswordAuthentication('[email protected]', 'password111');
    }
}

def  d_email = "[email protected]",
     d_uname = "[email protected]",
     d_password = "password111",
     d_host = "smtp.gmail.com",
     d_port  = "465", //465,587
     m_to = "[email protected]",
     m_subject = "Testing",
     m_text = "Hey, this is the testing email."

def props = new Properties()
props.put("mail.smtp.user", d_email)
props.put("mail.smtp.host", d_host)
props.put("mail.smtp.port", d_port)
props.put("mail.smtp.starttls.enable","true")
props.put("mail.smtp.debug", "true");
props.put("mail.smtp.auth", "true")
props.put("mail.smtp.socketFactory.port", d_port)
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory")
props.put("mail.smtp.socketFactory.fallback", "false")

def auth = new SMTPAuthenticator()
def session = Session.getInstance(props, auth)
session.setDebug(true);

def msg = new MimeMessage(session)
msg.setText(m_text)
msg.setSubject(m_subject)
msg.setFrom(new InternetAddress(d_email))
msg.addRecipient(Message.RecipientType.TO, new InternetAddress(m_to))

Transport transport = session.getTransport("smtps");
transport.connect(d_host, d_port, d_uname, d_password);
transport.sendMessage(msg, msg.getAllRecipients());
transport.close();

Works perfectly, Thank you very much!!!

I Faced an error while trying the above code which is
groovy.lang.MissingMethodException: No signature of method:
com.sun.mail.smtp.SMTPSSLTransport.connect()is applicable for argument types: (java.lang.String, java.lang.String, java.lang.String, java.lang.String) values: [smtp.gmail.com, 465, [email protected], password111] Possible solutions: connect(), connect(java.lang.String, java.lang.String, java.lang.String), connect(java.lang.String, int, java.lang.String, java.lang.String),connect(java.lang.String, java.lang.String), collect(), connect(java.net.Socket)
I fixed it by modifying parameters in transport.connect(d_host, d_port, d_uname, d_password); to transport.connect(d_host, d_port.toInteger(), d_uname, d_password);

Changing Line 29 to
d_port = 465, //465,587

Works better for me.
