SMSMTP

Single Mail SMTP tester.

A simple testing tool that stores exactly one email per recipient address and displays the contents in an HTML page served over a simple HTTP server.

Installation

npm install -g smsmtp

Start

smsmtp

Usage

Point your outbound SMTP setup for the server under test to 127.0.0.1:2525 (or whatever you set SMSMTP_BIND:SMSMTP_PORT to).

Use your server to send an email to some address, e.g. test@foo.com.

Point your browser to http://127.0.0.1:3000/test@foo.com (or whatever you set SMSMTP_HTTP_PORT:SMSMTP_HTTP_BIND to).

The server will keep only the last email sent to each recipient address in memory. No persistence, whatsoever.

Configuration

The server listens for connections on port 2525 (SMTP) and 3000 (HTTP). This can be overridden by setting the environment variables

  • SMSMTP_PORT for the SMTP listening port
  • SMSMTP_BIND for the SMTP bind address
  • SMSMTP_HOST for the SMTP hostname
  • SMSMTP_HTTP_PORT for the HTTP listening port
  • SMSMTP_HTTP_BIND for the HTTP bind address
  • SMSMTP_HTTP_HOST for the HTTP hostname

Credits

This is heavily inspired by Jonas Mosbech's /mail/null interactive SMTP testing tool. This package is reduced to the max, uses the successor of simplesmtp smtp-server and is optimized for streamlined CI testing.
