Features

This library is used at Crisp everyday to parse bounce emails. It supports most variations of bounce emails (Postfix, Dovecat, Gmail, Outlook).

Usage

const EmailBounceParse = require("email-bounce-parser");

const result = new EmailBounceParse().read(MY_EMAIL_STRING);

console.log(result);

API

Parse a bounce email

read(body) parses the bounce email and extracts available information (error code and type, server, original recipient, etc.):

• body must be a string representing the bounce email text body (not HTML body). You can use mailparser for example.

const EmailBounceParse = require("email-bounce-parser");

const result = new EmailBounceParse().read(MY_EMAIL_STRING);

console.log(result);
// {
//   bounce: true,
//
//   email: {
//     body: "This is the mail system at host mailer.acme.email [...] (in reply to RCPT TO command)",
//     intro: "This is the mail system at host mailer.acme.email [...] The mail system",
//     error: "<john@yipee.com>: host smtp.secureserver.net[92.240.81.0] said: [...] (in reply to RCPT TO command)"
//   },
//
//   data: {
//     error: {
//       code: {
//         basic: "550",
//         enhanced: "5.1.1"
//       },
//       label: "<john@yipee.com> Recipient not found.",
//
//       type: "action_not_taken",
//
//       temporary: false,
//       permanent: true,
//
//       data: {
//         type: "no_such_user",
//         blocked: false,
//         spam: false
//       }
//     },
//
//     recipient: "john@yipee.com",
//
//     server: {
//       hostname: "smtp.secureserver.net",
//       ip: "92.240.81.0",
//       port: "25"
//     },
//
//     command: "RCPT TO"
//   }
// }
