Simple Java Mail is the simplest to use lightweight mailing library for Java, while being able to send complex emails including authenticated socks proxy(!), attachments, embedded images, custom headers and properties, robust address validation, build pattern and even DKIM signing and external configuration files with property overriding, Spring support and Email conversion tools. Just send your emails without dealing with RFC's.
The Simple Java Mail library is a thin layer on top of the JavaMail smtp mailing API that allows users to define emails on a high abstraction level without having to deal with mumbo jumbo such as 'multipart' and 'mimemessage'.
(starting from v5.0.0)
EmailBuilder.startingBlank() EmailBuilder.replyingTo(email) EmailBuilder.forwarding(email) EmailBuilder.copying(email)
ConfigLoader.loadProperties("simplejavamail.properties"); // optional default ConfigLoader.loadProperties("overrides.properties"); // optional extra // almost everything is optional: Email email = EmailBuilder.startingBlank() .to("lollypop", "email@example.com") .to("C. Cane", "firstname.lastname@example.org") .ccWithFixedName("C. Bo group", "email@example.com", "firstname.lastname@example.org") .withRecipientsUsingFixedName("Tasting Group", BCC, "email@example.com;firstname.lastname@example.org;tester <email@example.com>") .bcc("Mr Sweetnose <firstname.lastname@example.org>") .withReplyTo("lollypop", "email@example.com") .withSubject("hey") .withHTMLText("<img src='cid:wink1'><b>We should meet up!</b><img src='cid:wink2'>") .withPlainText("Please view this email in a modern email client!") .withEmbeddedImage("wink1", imageByteArray, "image/png") .withEmbeddedImage("wink2", imageDatesource) .withAttachment("invitation", pdfByteArray, "application/pdf") .withAttachment("dresscode", odfDatasource) .withHeader("X-Priority", 5) .withReturnReceiptTo() .withDispositionNotificationTo("firstname.lastname@example.org") .withBounceTo("email@example.com") .signWithDomainKey(privateKeyData, "somemail.com", "selector") .buildEmail(); Mailer mailer = MailerBuilder .withSMTPServer("smtp.host.com", 587, "firstname.lastname@example.org", "password") .withTransportStrategy(TransportStrategy.SMTP_TLS) .withProxy("socksproxy.host.com", 1080, "proxy user", "proxy password") .withSessionTimeout(10 * 1000) .clearEmailAddressCriteria() // turns off email validation .withProperty("mail.smtp.sendpartial", true) .withDebugLogging(true) .buildMailer(); mailer.sendMail(email);

Also see the migration notes
- #116 You can now test the connection to the SMTP server
- #115 Create mailers with a very robust MailerBuilder API, able to ignore defaults as well
- #114 Create emails with a very robust EmailBuilder API, able to ignore defaults as well. Now includes support for InternetAddress. Also copy emails.
- #107 You can now easily forward or reply to emails!
- #111 Protocol properties for SMTPS are now applied properly
- #105 SMTP tries to upgrade to TLS while SMTP_TLS now enforces it and for both SMTP_TLS and SMTPS, mail.smtp.ssl.checkserveridentity is set to true
Complete Javadoc overhaul. Navigating the Javadoc should be much more consistent now (builder API being the single public source of truth).
- #120 The DKIM library has been made an optional proper Maven dependency (not packaged along anymore)
- #119 Switched optional Spring dependency version to property and now testing with 4.3.11.RELEASE
- #113 Updated the underlying JavaMail to 1.6.0
- #110 Trusted hosts should be space-delimited
- #109 Email headers should be allowed to be empty (now conversion errors can occur as well)
- #103 Converting to MimeMessage results in an invalid Content-Disposition for attachments
- #101 API backwards compatibility update, reinstate old addRecipient API as deprecated (sorry for removing it abruptly)
API usability release. This relase streamlined the recipient setters, breaking backwards compatibility (but straightforward to fix)
- #95 Feature: Add support native API for setting Return-Receipt-To header
- #93 Feature: Add support native API for setting Disposition-Notification-To header
- #91 Feature: Add support for parsing preformatted email addresses that include both name and address
- #94 Bugfix: A single EmailBuilder would build emails that all share the same collections for recipients, attachments and embedded images
- #98 Bugfix: Subject and body content should be optional
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.
- #89 Support multiple delimited recipient addresses sharing the same TO/CC/BCC name
- #88 Safeguard subject property (and others) against SMTP CRLF injection attacks
- #85 Apply configurable timeouts when sending emails
- #83 Parse INLINE attachments without ID as regular attachments when converting (mostly applicable to Apple emails)
#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.
- #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.
Patch: streamlined convenience methods for adding recipients.
Major feature: Using the EmailConverter you can now convert between Outlook .msg, EML, MimeMessage and Email!
- #66: Feature: convert email to EML

- #69: Enhancement: Expanded EmailBuilder API to inlude more options for setting (multiple) recipients
- #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
