SMTP

Netty is an asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers and clients.

SubEtha SMTP is an easy-to-use server-side SMTP library for Java.

Wiser is a smart mail testing application.

Apache Commons Net library contains a collection of network utilities and protocol implementations. Supported protocols include Echo, Finger, FTP, NNTP, NTP, POP3(S), SMTP(S), Telnet, and Whois.

James Protocols

Apache James Mail Server

Smtp modules for Guice implementation of James server

A multithreaded standalone SMTP mail server implementation.

The Apache Java Enterprise Mail Server (a.k.a. Apache James) is a 100% pure Java SMTP, IMAP, JMAP and POP3 Mail server. We have designed James to be a complete and portable enterprise mail engine solution based on currently available open protocols. James is also a mail application platform. We have developed a Java API to let you write Java code to process emails that we call the mailet API. A mailet can generate an automatic reply, update a database, prevent spam, build a message archive, or whatever you can imagine. A matcher determines whether your mailet should process an email in the server. The James project hosts the Mailet API, and James provides an implementation of this mail application platform API.

Jakarta Mail API distribution

Simple API, Complex Emails. A light weight wrapper for the JavaMail SMTP API

A Mule transport for Email Connectivity. This transport supplies a Pop3 connector, Smtp connector and a Mail connector which is an aggregation of the two.

Provide a standalone mock SMTP server that could be configured over HTTP. Dockerized it can be used for advanced error testing for SMTP clients.

The Apache Java Enterprise Mail Server (a.k.a. JAMES Server)

This feature allows applications to interact with an external mail server by using the JavaMail 1.5 API, which provides common store and transport protocols, such as POP3, IMAP, and SMTP.

Functional test framework specialised for the ASCII line-base protocols common in mail.

This feature allows applications to interact with an external mail server by using the JavaMail 1.6 API, which provides common store and transport protocols, such as POP3, IMAP, and SMTP.

niosmtp is an async based SMTP/LMTP client, which can be used to send an big amount of emails in a fast manner. The transport layer is decoupled from the protocol logic, this allows easy implementing of an other transport layer. Included is a NIO and OIO based transport layer build on top of netty.
