you need use nodemailer-smtp-pool module, , provide email server credential in option:

var mailer = require('nodemailer'); var smtppool = require('nodemailer-smtp-pool'); var option = {     host: 'localhost',     port: 25,     auth: {         user: 'your@email.com',         pass: 'yourpassword'     } }  mailer.createtransport(smtppool(option));  ... // send email mailer.sendmail(...) 

that it.
