• #​684: corrected the S/MIME configuration example to use a valid message-content cipher.
• #​683: moved CLI-only recipient parsing out of EmailPopulatingBuilder without changing CLI behavior.
• #​680: made S/MIME signature status represent only verification that actually occurred and preserve failed combined results.
• #​679: rejected DKIM configurations that exclude the mandatory From header.
• 55586ee6: added explicit file: and base64: DKIM private-key sources while preserving unprefixed values.
• #​678: contained embedded-image auto-resolution within configured file, classpath, and URL bases.
• #​677: replaced trust-all TLS defaults with the JVM trust store while retaining hostname verification.
• #​676: bound the authenticated SOCKS bridge to JVM loopback instead of wildcard interfaces.

v9.1.0 - v9.1.8 - Maven Central

Spring-module notice: Versions 9.0.0 through 9.1.5 package test application settings that can override an application's YAML configuration and prevent SMTP connections. If you use spring-module, upgrade to 9.1.6 or later.

CLI recipient notice: Versions 9.0.0 through 9.1.6 cannot combine TO, CC, and BCC recipients in one CLI command. Repeated --email:withRecipients options are merged and rejected. Upgrade to 9.1.7 or later.

• v9.1.8: #​686: Custom-session proxy routing: usingSession(session).withProxy(...) now updates the intended mail.smtp.socks.* route while leaving the rest of the caller's session configuration untouched.
• v9.1.8: #​687: SMTPS through SOCKS: removed the obsolete restriction that rejected SOCKS proxying for implicit-TLS SMTP connections.
• v9.1.8: #​696, #​697: Connection-pool resets: the max-size and claim-timeout reset methods now restore their own settings without changing the core size or connection expiry.
• v9.1.7: #​682: Dedicated CLI recipient options: restore independent --email:to, --email:cc, and --email:bcc options so one command can combine all three recipient types.
• v9.1.6: #​681: Spring configuration isolation: stop packaging the Spring test application.properties in spring-module. Sample local-bind, SMTP client-hostname, transfer-encoding, and other test values can no longer override an application's YAML configuration or break SMTP connections.
• v9.1.5: #​674, #​675: SOCKS5 domain framing: place the port after the UTF-8-encoded domain bytes and decode domain replies after their length octet, fixing internationalized-host requests and reply diagnostics.
• v9.1.4: #​669, #​670: EML file stream ownership: close streams created internally by the File-based EML conversion overloads after synchronous parsing, while leaving caller-provided InputStream ownership unchanged.
• v9.1.4: Java 8-compatible dependency and release-tool maintenance: updated SpotBugs annotations to 4.10.3 (#​671), the Central Publishing Maven Plugin to 0.11.0 (#​672), and Objenesis to 3.6 (#​673).
• v9.1.3: #​668: New Outlook inline images: updated outlook-message-parser to 1.16.2 so native-HTML-only .msg files match inline cid: images correctly and trailing NUL terminators no longer leak into attachment metadata.
• v9.1.2: Dependency and Java 8-compatible build-tool maintenance: updated JMail to 2.2.0 (#​663), Zip4j to 2.11.6 (#​666), Exec Maven Plugin to 3.6.3 (#​664), Maven Enforcer Plugin to 3.6.3 (#​665), and Maven JAR Plugin to 3.5.1 (#​667).
• v9.1.1: Java 8 build-tool maintenance (#​662): updated annotations and Maven compiler, JAR, OSGi bundle, and Karaf tooling to Java 8-compatible versions, with Dependabot guards against newer-Java-only upgrade lines.
• v9.1.0: #​653: a configurable SMTP client hostname for the EHLO / HELO command.
• v9.1.0: #​654: SMTP submission receipts for reading the server acceptance response after a send.
• v9.1.0: No breaking changes; existing sendMail(...) behavior is unchanged.

v9.0.0 - v9.0.4 - Maven Central

Spring-module notice: Versions 9.0.0 through 9.1.5 package test application settings that can override an application's YAML configuration and prevent SMTP connections. If you use spring-module, upgrade to 9.1.6 or later.

The Short Version

Simple Java Mail has been going strong-ish for about 20 years, and 9.0.0 rolls roughly two years of backlog into a new major release.

simple-java-mail
└── outlook-message-parser
    └── rtf-to-html
└── java-utils-mail-dkim
└── java-utils-mail-smime
└── smtp-connection-pool
    └── clustered-object-pool
        └── generic-object-pool
└── java-socks-proxy-server

Across Simple Java Mail and the supporting libraries that keep the stack moving, more than 100 GitHub issues and PRs were reviewed, fixed, merged, or closed while keeping the project Java 8-compatible.

Major features: the dedicated recipient builder API, per-recipient S/MIME certificates, first-class Delivery Status Notification support, pre-encoded attachment and embedded-image sending, mailer-level DKIM defaults, and simple batch/open-connection sending without the batch module.
Enhancements: broader Outlook conversion metadata, MIME resource handling, content-transfer encoding control, debug routing, local SMTP bind configuration, batch cluster configuration, and Java module support.

Migration Note

This is a breaking major release. The old recipient-addition method jungle has been cleaned up in favor of the recipient builder API, so code that relied on the removed recipient overloads needs to migrate. Start with the 9.0 migration notes before upgrading.

Major Features

• v9.0.0: #​613: Recipient builder API: added dedicated builders for constructing single recipients and recipient collections.
• v9.0.0: #​297: Per-recipient S/MIME certificates: enabled encrypted mail for multiple recipients with different certificates.
• v9.0.0: #​574: Delivery Status Notification (DSN): added first-class DSN configuration.
• v9.0.0: #​573: Pre-encoded resources: added pre-encoded attachment and embedded-image APIs.
• v9.0.0: #​196: Mailer-level DKIM defaults: added default DKIM signing configuration so DKIM can be configured once per Mailer.
• v9.0.0: #​569: Simple batch and open-connection sending: added sendMailsInSimpleBatch(...) for sequential batch work without the batch module and withOpenConnection(...) for callback-scoped reuse of a single SMTP connection.

Enhancements

• v9.0.2: #​645: Outlook last-modifier metadata: exposed PR_LAST_MODIFIER_NAME / 0x3FFA as OutlookMessageData#getLastModifierName() without treating it as sender identity.
• v9.0.0: #​614: Outlook conversion metadata: added explicit result APIs for inspecting source .msg headers and metadata without copying structural headers into converted emails, resolving #​609.
• v9.0.0: #​605: Per-body content-transfer encoding: added Content-Transfer-Encoding configuration for plain text, HTML, and calendar content.
• v9.0.0: #​566, #​597, #​602, #​607: MIME resource Content-ID handling: improved explicit IDs, parsed embedded images, and generated fallback IDs.
• v9.0.0: #​589: Jakarta Mail debug output: added configurable debug output routing.
• v9.0.0: #​568: Local SMTP bind address: added configuration for multi-IP SMTP hosts.
• v9.0.0: #​565, #​618: Batch cluster configuration: fixed Java API cluster configuration and added property-defined cluster configurations for property-file and Spring-configured clustered sending.
• v9.0.0: #​572, #​571: S/MIME conversion leniency: tolerate unsupported S/MIME payloads during Outlook conversion and preserve parsed email content when signature verification fails.
• v9.0.0: #​606: MIME type sanitizing: sanitize malformed resource MIME types before generating attachment and embedded-image headers.
• v9.0.0: #​541: Resource headers: removed the non-standard filename parameter from resource Content-Type headers; filenames remain available through Content-Disposition.
• v9.0.0: #​265, #​237: Java module support: added Java 9 module descriptors to the core and facade jars so modular applications can require org.simplejavamail directly.

Fixes and Compatibility

• v9.0.4: #​652: RFC 2047 address validation: reject encoded-word syntax inside address specs during validation while keeping encoded display names valid.
• v9.0.3: #​651: Outlook plain-text RTF rendering: preserved line breaks without exposing browser-default <pre> styling in converted HTML.
• v9.0.0: #​615: Async test connections: fixed MailerGenericBuilder.async() so no-arg testConnection() uses the configured async default.
• v9.0.0: #​611: SMTPS custom SSL socket factories: fixed custom SSL socket factory configuration for SMTPS mailers.
• v9.0.0: #​535: Async failure reporting: let async send and connection-test failures surface through the returned CompletableFuture without duplicate framework error logs.
• v9.0.0: #​583: Java 25 CLI startup: fixed CLI startup on Java 25.
• v9.0.0: #​616: CLI optional-argument detection: removed the runtime JetBrains annotation fork from CLI optional-argument detection.
• v9.0.0: Standalone CLI command cleanup: send, connect, and validate now wait for command work and close mailer resources, preventing batch-module resources from keeping the process alive.

Dependency and Supporting-Library Updates

• v9.0.3: Angus runtime alignment: bumped Angus Mail to 2.0.5 and added Angus Activation 2.0.3.
• v9.0.3: Logging dependencies: bumped Log4j from 2.25.4 to 2.26.1.

• v7.9.0 (21-February-2023): #​344 Enhancement: make DKIM signing more flexible by allowing header exclusions in DKIM signature

v7.8.0 - v7.8.3

• v7.8.3 (21-February-2023): #​293 Bugfix: Decoding missing in a few placed when parsing MimeMessage or sending an Email
• v7.8.2 (09-February-2023): #​442 Enhancement: Simple Java Mail should throw an exception when trying to utilize S/MIME with smime-module on the classpath
• v7.8.1 (01-February-2023): #​438 Bug: properly Fail-Fast in case of Transport claim timeout in the batch-module, rather than running into NPE further down the line
• v7.8.0 (24-January-2023): #​436 Enhancement: add mailerBuilder.withTransportModeLoggingOnly() as mailer API entry point
• v7.8.0 (24-January-2023): #​435 Enhancement: SMTP server config should be optional in case a CustomMailer is used

• v7.7.0 (17-January-2023): #​383 Feature: be able to set defaults and overrides on the Mailer level, rather than email or global level

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).

v7.6.0 (05-January-2023)

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:

• simple-java-mail/java-utils-mail-smime
