Thank you for the script.
Please look at line 56. There is the fixed port number 465, but you have configuration variables.

Thank you. Great to know it helps you.
I have fixed it, but i think this is very dirty script to begin with :) lets see if i can make it better later.

I'm not able to reuse the code in my IntelliJ IDE, javax.mail is not recognised and shows compile error.Please help.

@pb60704, have you read this?

Thanks for this script, it provided some helpful information. I tried to whittle it down to the bare minimum of what was required (at least for my use case). And here it is, hopefully it can be helpful.

@Grab(group = 'com.sun.mail', module = 'javax.mail', version = '1.6.0')

import javax.mail.Message
import javax.mail.Session
import javax.mail.Transport
import javax.mail.internet.InternetAddress
import javax.mail.internet.MimeMessage

MAILER_HOST = "mailtrap.io"
MAILER_USER = "<user account>"
MAILER_PASS = "<password>"
MAILER_PORT = 2525

private void runScript() {
    Session session = Session.getDefaultInstance(new Properties())

    MimeMessage message = new MimeMessage(session)
    message.setFrom("[email protected]")
    message.setRecipient(Message.RecipientType.TO, new InternetAddress("[email protected]"))
    message.setSubject("Important message!")
    message.setText("Here is an important email message!")

    Transport transport = session.getTransport("smtp")
    transport.connect(MAILER_HOST, MAILER_PORT, MAILER_USER, MAILER_PASS)
    transport.sendMessage(message, message.getAllRecipients())
    transport.close()
}

runScript()

Thanks, guys! Here's a slightly shorter version that doesn't require SMTP AUTH... (probably only works if recipient domain is served by MAILER_HOST.

#!/usr/bin/env groovy

@Grab(group = 'com.sun.mail', module = 'javax.mail', version = '1.6.0')

import javax.mail.*
import javax.mail.internet.*

MAILER_HOST = "aspmx.l.google.com"  // "smtp-relay.gmail.com"
RECIPIENT_EMAIL = "[email protected]"
date_time = new Date().format("yyyy-MM-dd hh:mm")
props = new Properties()

private void runScript() {
    props.put("mail.host", MAILER_HOST);
    Session session = Session.getDefaultInstance(props)
    session.setDebug(true);

    MimeMessage message = new MimeMessage(session)
    message.setFrom("[email protected]")
    message.setRecipient(Message.RecipientType.TO, new InternetAddress(RECIPIENT_EMAIL))
    message.setSubject("A Test email ${date_time}")
    message.setText("This is a sample email message!")

    Transport.send(message)
}

runScript()

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.
