sending mail with nodemailer

问题

whenever i run the code I'm getting the error " Error: Greeting never received at SMTPConnection._formatError...."

function automatedMailSender(req,res){

var mailOptions = {
    from: "abc <abc@test.com>", // sender address
    to: 'nit@test.com', // list of receivers
    subject: 'Hello ', // Subject line
    text: 'Hello world ?', // plain text body
    html: '<b>Hello world ?</b>' // html body
 };


var mailer=nodemailer.createTransport({
    host: 'mail.test.com',
    port: 465,
    secure: false, // secure:true for port 465, secure:false for port 587
    auth: {
        user: 'mymail@test.com',
        pass: '1234'
    }
});

mailer.sendMail(mailOptions, (error, response)=>{
    if(error){
        console.log('mail not sent \n',error);
    }
    else{
        console.log("Message sent: " ,response.message);
    }   
 });
}

I'm I doing something wrong in the code.

回答1:

The answer in right in your code

port: 465,
secure: false, // secure:true for port 465, secure:false for port 587

The value for "secure" should be true for port 465

回答2:

This is due to your SMTP security for unauthorised user so for overcome this problem you need set rejectUnauthorized:false

Hope this will helpyou.

回答3:

If you are using Gmail to send mails then try this.

Allow less secure apps to connect to Gmail.

回答4:

tls:{
        rejectUnauthorized:false
    }

fixed it by using the above code in mailer variable. Thanks guys

Try something like that, it work perfectly for me:

//Create reusable transporter object using the default SMTP transport 
var transporter = nodemailer.createTransport(
'smtps://USERNAME%40gmail.com:PASSWORD@smtp.gmail.com');

// setup e-mail data 
var mailOptions = {
        from: '"Michel 👥" <recipe@example.com>', // sender address 
        to: 'bernard@example.com', // list of receivers 
        subject: 'Hello', // Subject line 
        text: 'Bonjour!' // plaintext body 
      };

// send mail with defined transport object

transporter.sendMail(mailOptions, function(error, info){
      if(error){
        return console.log(error);
      }
      console.log('Message sent: ' + info.response);
});

If is still doesn't work you have a little tuto here

var mailer=nodemailer.createTransport({
    host: 'mail.test.com',
    port: 465,
    secure: true, // secure:true for port 465, secure:false for port 587
    transportMethod: 'SMTP',
    auth: {
        user: 'mymail@test.com',
        pass: '1234'
    }
});

The value for secure should be true for port 465 and use transportMethod: 'SMTP'
