Node.js nodemailer error - wrong version number/invalid greeting

I have a big problem with setting up the nodemailer on my node.js server. Tried everthing I found on the internet but nothing works. The only thing that was easy to setup was the gmail service. but unfortunately I cannot use that one.

With secure set to true, i get an ssl error with the reason wrong version code.

[Error: 22468:error:1408F10B:SSL routines:ssl3_get_record:wrong version number:c:\ws\deps\openssl\openssl\ssl\record\ssl3_record.c:332:
] {
  library: 'SSL routines',
  function: 'ssl3_get_record',
  reason: 'wrong version number',
  code: 'ESOCKET',
  command: 'CONN'
}

But when I try to set secure to false, then I get an invalid greeting error.

}

My code is the following:

const transporter = nodemailer.createTransport({
  host: process.env.MAIL_HOST, // mx.example.com
  port: process.env.MAIL_PORT, // 143
  secure: true,
  auth: {
    user: process.env.MAIL_ADDRESS,
    pass: process.env.MAIL_PWD
  }
})

I checked the credentials a thousand time, they are definetly not the problem.

Hope anyone can help me. Thanks in advance.

Solution

  • Refering to this issue mentioned here: https://github.com/nodemailer/nodemailer/issues/165

    See if this helps, adding the tls.ciphers option to use SSLv3:

    const transport = nodemailer.createTransport({
    host: process.env.MAIL_HOST, // mx.example.com
    port: process.env.MAIL_PORT, // 143
    secureConnection: false, // TLS requires secureConnection to be false
    auth: {
        user: process.env.MAIL_ADDRESS,
        pass: process.env.MAIL_PWD
    },
    tls: {
        ciphers:'SSLv3'
    }
});

    For Outlook365, this should work:

    service: "Outlook365",
auth: {
   user: '[YOUR_O365_EMAIL]',
   pass: '[YOUR_O365_PASSWORD]'
},

    If you're using HotMail, then remove host and port, and just add service: "hotmail".
