在不使用 gmail smtp 的情况下发送电子邮件 nodemailer

如何解决在不使用 gmail smtp 的情况下发送电子邮件 nodemailer

我有一个使用 bell.net 电子邮件地址的企业电子邮件，在他们的网站上，它说使用 smtphm.sympatico.ca 作为 smtp 主机名，以及 port 25 / 587...我有我的nodemailer 代码设置如下：

 app.post('/sendBatchEmail',(req,res) => {
    var emails = [];
    var emailSubject = req.body.emailSubject;
    var emailMessage = req.body.emailMessage;

    //perform db2 send
    var sendEmail = "select * from testemails"
    ibmdb.open(ibmdbconnMaster,function (err,conn) {
      if (err) return console.log(err);
      conn.query(sendEmail,rows) {
        if (err) {
          console.log(err);
        }
        for (var i = 0; i < rows.length; i++) {
          emails.push(rows[i].EMAIL)
        }
       
        //send email
        async function main() {
          
          let transporter = nodemailer.createTransport({
            host: "smtphm.sympatico.ca",port: 25,secure: false,// true for 465,false for other ports
            auth: {
              user: "[e-mail]",pass: "xxx",},});
      
          // send mail with defined transport object
          let sendBatch = await transporter.sendMail({
            from: "[e-mail]",// sender address
            to: "[e-mail]",bcc: emails,// list of receivers
            subject: emailSubject,// Subject line
            text: emailMessage,// plain text body
          });
          
      
          console.log("Message sent: %s",sendBatch.messageId);
          // Message sent: <[e-mail]>
      
          // Preview only available when sending through an Ethereal account
          // console.log("Preview URL: %s",sendBatch.getTestMessageUrl);
          // Preview URL: https://ethereal.email/message/WaQKMgKddxQDoou...
        }
      
        main().catch(console.error);
        res.redirect("/");

        conn.close(function () {
          console.log("closed the function app.get(/sendEmailBatch)");
        });
      });
    });

  })

但是，这不起作用并给我这个错误：

    Error: Invalid login: 535 Authentication Failed

}

但是当我将其改回 gmail 时有效...有什么想法吗？
