Error sending email using nodemailer via Office365 smtp (MEANjs scaffold)

问题

I'm trying to use Office365 SMTP to send email using Nodemailer (in a MEANjs scaffold), but I get the following error:

[Error: 140735277183760:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol:../deps/openssl/openssl/ssl/s23_clnt.c:795:]

I'm using the following Nodemailer options:

{ 
    host: 'smtp.office365.com',
    port: '587',
    auth: { user: 'xxxx', pass: 'xxxx' },
    secure: 'false',
    tls: { ciphers: 'SSLv3' }
}

Removing the tls field doesn't make a difference. What am I missing?

回答1:

The solution was simple. The 'secure' field should be 'secureConnection'. The MEANjs scaffold that generated the configs created mailer options with the 'secure' field. The rest of the options are fine. For anyone that needs a working Office365 SMTP nodemailer options block, the following should work:

{ 
    host: 'smtp.office365.com',
    port: '587',
    auth: { user: 'xxxx', pass: 'xxxx' },
    secureConnection: false,
    tls: { ciphers: 'SSLv3' }
}

This nodemailer documentation https://nodemailer.com/2-0-0-beta/setup-smtp/ indeed states options.secure and not options.secureConnection. It also suggests, in an example, that options.secure is expecting a boolean value true or false and not a string value 'true' or 'false'. Removing the '' from around 'false' works for me.

I know this is old but if anyone looks this up in 2019, you can just add service: "Outlook365"

and you won't have to specify connection options.

Node Mailer Docs

let transporter = nodemailer.createTransport({
    service: "Outlook365",
    auth: {
      user: 'FROMUSER@office365.com',
      pass: 'FROMUSERPASS'
    },    
  })

  let info = transporter.sendMail({
    from: 'FROMUSER@office365.com',
    to: 'TOUSER@office365.com',
    subject: 'Test',
    text: 'hello world',
    html: '<h1>TEST</h1>'
  })
