无法使用nodemailer从linux服务器发送邮件

Question

i am trying to send mail after user gets registered. I am using nodemailer for this. my code for this look like this-

 var transporter = nodemailer.createTransport({
  service:"Mailjet", // sets automatically host, port and connection security settings
    auth: {
    user:'******',
    pass:'*******'
  }
});
var mailOptions = {
  to:mailTo,
  from:'******',
  subject:'user registered',
  text:'welcome user'
};
transporter.sendMail(mailOptions, function(err, info) {
  if (err) {
    logger.debug('error in sending email ' + err);
  } else {
    logger.debug('Message sent: ' + info.response);
  };

Mail is going properly when i use this on my localhost on my window machine but when i use this on my remote server which is a linux server. I get the following error :

error--- { Error: Connection timeout at SMTPConnection._formatError (/root/root/server/cq-code/node_modules/nodemailer/lib/smtp-connection/index.js:557:19) at SMTPConnection._onError (/root/root/server/cq-code/node_modules/nodemailer/lib/smtp-connection/index.js:530:20) at Timeout._connectionTimeout.setTimeout (/root/root/server/cq-code/node_modules/nodemailer/lib/smtp-connection/index.js:248:18) at ontimeout (timers.js:471:11) at tryOnTimeout (timers.js:306:5) at Timer.listOnTimeout (timers.js:266:5) code: 'ETIMEDOUT', command: 'CONN' } info----- undefined

代码工作正常。问题出在服务器上，实际上用于 SMTP 的端口被数字海洋阻止了。所以我向他们提出了一个问题，在解除阻止该端口后，事情按预期进行。
