Simple Java Mail
Simple Java Mail is the simplest to use lightweight mailing library for Java, while being able to send complex emails including Batch processing and server clusters, CLI support, authenticated socks proxy(!), attachments, embedded images, custom headers and properties, robust address validation, build pattern and even DKIM signing, S/MIME support and external configuration files, Spring support and Email conversion tools (including support for Outlook).
Just send your emails without dealing with RFCs.
The Simple Java Mail library is a thin layer on top of Angus Mail (previously Jakarta Mail) that allows users to define emails on a high abstraction level without having to deal with mumbo jumbo such as 'multipart' and 'mimemessage'.
Simple Java Mail is available in Maven Central:
<dependency>
<groupId>org.simplejavamail</groupId>
<artifactId>simple-java-mail</artifactId>
<version>8.12.2</version>
</dependency>

NOTE: release 8.8.0 changes the default for DKIM signing from 'l-param' true to false. If you rely on this feature, you need to enable it explicitly. Refer to the DKIM documentation for the update.
v8.7.0 - v8.7.1
- v8.7.1 (20-March-2024): #498: Make S/MIME algorithms configurable (signature algorithm for signing, key encapsulation and cipher algorithms for encryption)
- v8.7.1 (20-March-2024): #497: Order of attachments is lost when converting a MimeMessage to an Email
- v8.7.0 (20-March-2024): don't use this version: versioning messed up

v8.6.0 - v8.6.3

One known issue is that Angus, since 1.1.0, performs server identity checks by default, which was previously disabled for SMTP. If you encounter issues with this, you can disable it with mailerBuilder.verifyingServerIdentity(false) and starting from 8.8.2, this also works with SMTP transport strategy (see #495).

7.7.0 moves the conversion of Email to MimeMessage to after a Transport instance has been selected (in case of a cluster of SMTP servers),
so we can apply defaults/overrides on the Mailer level, meaning you can configure 'global' values for individual SMTP servers
(like a fixed FROM per server).

About the migration
Updating to Java8/Jakarta 2.0.1 posed a challenge as the 3rd party S/MIME library java-utils-mail-smime has been abandoned/archived while developing Simple Java Mail. Furthermore, it was still under LGPL3 license while everything else is ApacheV2.
Thankfully, I obtained permissions from the maintainers -as well as original developers from decades ago on SourceForge- to take both java-utils-mail-smime and java-utils-mail-dkim under my wings at Simple Java Mail and change the licensing model! You can now post issues and pull requests here:

A big shout-out to @dnault (runtime javadoc), @remkop (picocli) and @markenwerk
(S/MIME and DKIM) for working with me to make the
libraries work with JDK7+ and do what Simple Java Mail needed! Finally, a great many thanks the numerous contributors on Simple Java Mail as well as
outlook-message-parser - this release would not be there without you.

API usability release. This relase streamlined the recipient setters, breaking backwards compatibility (but straightforward to fix)
v4.3.0 (12-August-2017)
Security and timeout release.
This version safeguards against SMTP injection attack from external values entering the library through Email instance. Also, this release introduces default/configurable timeouts for connecting, reading and writing when sending an email.

v4.2.3 (21-May-2017)
-
#79: Enhancement: define custom message ID on the Email object
-
#74: v4.2.3-java-6-release: A java6 version with limited capabilities:
I've released a customised java6 release with a customised outlook-message-parser 1.1.16-java6-release. This is the last java6 release I will do, as it is simply too much manual labor to create a limited second edition.
For this edition, I've removed the JDK7 Phaser completely which has the following consequences:
- If authenticated proxy is used, the bridging proxy server will not be shut down automatically (and might not run the second time)
- If mails are sent in async mode, the connection pool will not be shut down anymore by itself
This means your server/application might not stop properly due to lingering processes. To be completely safe, only send emails in sync mode (used by default) and don't use authenticated proxy config.
v4.2.2 (10-May-2017)
- #73: Patch: fix for sending emails in async mode, which makes sure the connection pool is always closed when the last known email has been sent. Without this fix, the connection pool keeps any parent process running (main thread or Tomcat for example) until a hard kill.
v4.2.1 (12-Feb-2017)
Patch: streamlined convenience methods for adding recipients.
v4.2.0 (12-Feb-2017)

- #70: Enhancement: Most public API now have defensive null-checks for required fields (Fail Fast support)
- #68: Bugfix: Name should be required for embedded images (added safeguards)
- #67: Bugfix: Error when name was omitted for attachment
- minor: added methods on AttachmentResource that reads back the content as (encoded) String
- other: internal testing is now done using Wiser SMTP test server for testing live sending emails
