Node Mailer does not timeout when no respond from email provider

I am sending emails using nodemailer and it is working fine. Until in some cases when email service provider(in this case I am using outlook) does not respond with error or success. Which makes my mailing job waiting forever.

So I searched for possible timeout handling in nodemailer.

The timeouts available are these:

• connectionTimeout – how many milliseconds to wait for the connection to establish
• greetingTimeout – how many milliseconds to wait for the greeting after connection is established
• socketTimeout – how many milliseconds of inactivity to allow

But this timeouts doesn't help me solve my current problem.
