Configuring SMTP correctly for Node application

Posted By d_h_san_diego_us02/06/2019 08:21

I have a node application in which I'm trying to use nodemailer to send e-mail using Dynadot's SMTP server. Despite using the correct username/pw, I keep getting a "Invalid login: 535 authentication failed" error. I've turned on debugging and posted the output below: harpoon_1 | [2019-02-06 08:07:15] DEBUG Creating transport: nodemailer (5.1.1; +https://nodemailer.com/; SMTP/5.1.1[client:5.1.1]) harpoon_1 | [2019-02-06 08:07:15] DEBUG Sending mail using SMTP/5.1.1[client:5.1.1] harpoon_1 | [2019-02-06 08:07:15] DEBUG [VBRSeFNJQs] Resolved smtp.webhost.dynadot.com as 166.88.19.240 [cache miss] harpoon_1 | [2019-02-06 08:07:15] INFO [VBRSeFNJQs] Connection established to 166.88.19.240:25 harpoon_1 | [2019-02-06 08:07:15] DEBUG [VBRSeFNJQs] S: 220 webhost.dynadot.com ESMTP harpoon_1 | [2019-02-06 08:07:15] DEBUG [VBRSeFNJQs] C: EHLO [127.0.0.1] harpoon_1 | [2019-02-06 08:07:15] DEBUG [VBRSeFNJQs] S: 250-AUTH LOGIN harpoon_1 | [2019-02-06 08:07:15] DEBUG [VBRSeFNJQs] S: 250-STARTTLS harpoon_1 | [2019-02-06 08:07:15] DEBUG [VBRSeFNJQs] S: 250 8BITMIME harpoon_1 | [2019-02-06 08:07:15] DEBUG [VBRSeFNJQs] C: STARTTLS harpoon_1 | [2019-02-06 08:07:15] DEBUG [VBRSeFNJQs] S: 220 TLS go ahead harpoon_1 | [2019-02-06 08:07:15] INFO [VBRSeFNJQs] Connection upgraded with STARTTLS harpoon_1 | [2019-02-06 08:07:15] DEBUG [VBRSeFNJQs] C: EHLO [127.0.0.1] harpoon_1 | [2019-02-06 08:07:15] DEBUG [VBRSeFNJQs] S: 250 8BITMIME harpoon_1 | [2019-02-06 08:07:15] DEBUG [VBRSeFNJQs] SMTP handshake finished harpoon_1 | [2019-02-06 08:07:15] DEBUG [VBRSeFNJQs] C: AUTH PLAIN AGluZm9AaGFycG9vbmNvcnAuaW8AdGVzdDEyMzQ= harpoon_1 | [2019-02-06 08:07:15] DEBUG [VBRSeFNJQs] S: 535 authentication failed harpoon_1 | [2019-02-06 08:07:15] INFO [VBRSeFNJQs] User "info@harpooncorp.io" failed to authenticate harpoon_1 | [2019-02-06 08:07:15] DEBUG [VBRSeFNJQs] Closing connection to the server using "end" harpoon_1 | [2019-02-06 08:07:15] ERROR Send Error: Invalid login: 535 authentication failed harpoon_1 | { Error: Invalid login: 535 authentication failed harpoon_1 | at SMTPConnection._formatError (/usr/src/app/node_modules/nodemailer/lib/smtp-connection/index.js:774:19) harpoon_1 | at SMTPConnection._actionAUTHComplete (/usr/src/app/node_modules/nodemailer/lib/smtp-connection/index.js:1509:34) harpoon_1 | at SMTPConnection._responseActions.push.str (/usr/src/app/node_modules/nodemailer/lib/smtp-connection/index.js:547:26) harpoon_1 | at SMTPConnection._processResponse (/usr/src/app/node_modules/nodemailer/lib/smtp-connection/index.js:933:20) harpoon_1 | at SMTPConnection._onData (/usr/src/app/node_modules/nodemailer/lib/smtp-connection/index.js:739:14) harpoon_1 | at TLSSocket._socket.on.chunk (/usr/src/app/node_modules/nodemailer/lib/smtp-connection/index.js:879:55) harpoon_1 | at emitOne (events.js:116:13) harpoon_1 | at TLSSocket.emit (events.js:211:7) harpoon_1 | at addChunk (_stream_readable.js:263:12) harpoon_1 | at readableAddChunk (_stream_readable.js:250:11) harpoon_1 | at TLSSocket.Readable.push (_stream_readable.js:208:10) harpoon_1 | at TLSWrap.onread (net.js:594:20) harpoon_1 | code: 'EAUTH', harpoon_1 | response: '535 authentication failed', harpoon_1 | responseCode: 535, harpoon_1 | command: 'AUTH PLAIN' } harpoon_1 | [2019-02-06 08:07:15] INFO [VBRSeFNJQs] Connection closed Additionally, the code I'm using to configure is below for your reference: const smtpTransport = nodemailer.createTransport({ host: "smtp.webhost.dynadot.com", port: 25, secure: false, requireTLS: true, logger: true, debug: true, tls: {rejectUnauthorized: false}, auth: { user: 'info@harpooncorp.io', pass: '**************' } });

Sorry for the delay on this response. Unfortunately as nodemailer is a 3rd party software so we would not be able to trouble shoot it for you. We suggest looking directly on their site for any information that may help you.
