Any suggestion for smtp mail server in nodejs?

Question

I googled out quite a few but all are at best alpha versions, so it seems I will have to try an code one. Instead of coding one from scratch I would like to build on existing implementation, but a good one.

Any suggestions?

Answer 1

Haraka: https://github.com/baudehlo/Haraka

Is a full featured mail server in node.js - should do everything that you need.

Answer 2

Personally, I use node_mailer :

send emails from node.js to your smtp server, simple as cake.

From https://github.com/marak/node_mailer :

Features :

• super simple api
• emails are blasted out asynchronously
• uses connection pooling per SMTP server
• super simple built in templates using Mustache.js
• SSL supported (NodeJS v0.3.x or later)

Answer 3

RFC 2821 (http://tools.ietf.org/html/rfc2821) is not too complex, you should be able to flesh out a server in about 300 lines of js.

Answer 4

Some answers here are quite outdated, so I'd like to offer the lastest.

There are currently three Node SMTP servers (libraries) I know of:

• Haraka (which has been mentioned and is quite robust/heavy)
• smtp-server (this is the successor to the deprecated Simple SMTP project)
• smtp-protocol

There's also mailin which is an SMTP server that receives messages and posts them to some URL for you to process. Mailin uses Python for some optional features.

SMTP server - I've used Simple SMTP in conjunction with mailparser. IMHO, these are the best tools on the Internet for building SMTP servers in Node.js.

UPDATE: Simple SMTP has been deprecated. Use SMTP server instead (the successor of the Simple SMTP module).
