Changes

3.1.7 - June 12, 2012

  • Complete Maven build (in addition to the original Ant based build)
  • SLF4J upgraded from the 1.5 series to 1.6
  • More graceful shutdown: SMTPServer.stop waits until all connections finish their work.
  • Issue 45: AUTH LOGIN authentication is compatible with the .NET SMTP library. Patch by Reid Nimz.
  • AUTH command replies with specific error messages if something goes wrong.
  • Issue 46: Suebetha loses session.helo after first email.
  • Case-sensitivity issue with the AUTH command
  • Build-time libraries are placed into a separate directory.
  • Issue 47: MessageHandler lifecycle better matches its purpose: following a single mail transaction within a full session. HELO and EHLO resets the mail transaction in progress.
  • Issue 48: Use ExecutorService instead of new Thread. Patch from Eric Parusel.
  • Possible concurrency issue on connection shutdown.
  • Issue 49: No error if server is running already
  • Improved Javadoc about authentication
  • SMTP session identifier is generated and included in the Received header and in the logging context.

3.1.6 - June 23, 2011

  • Issue 39
  • Issue 40
  • More error handling in SMTPClient when a broken server does not send a reply at all
  • Received header now does not contain a second source domain name string in the address part, so it conforms to the RFC. In addition, if the address cannot be resolved to a domain name then it does not print the address in place of the domain name, but simply omits that part according to the RFC.
  • ReceivedHeaderStream adds a FOR Single-recipient clause to the Received header when there is only a single accepted recipient in the mail transaction.
  • ReceivedHeaderStream shows sofware name and version, as they are set in SMTPServer
  • Logging of RuntimeException and Error throwables in the session thread. This is in addition to the UncaughtExceptionHandler which is set by the JRE or by the application. The default handler installed in the JRE prints such exceptions to STDERR.
  • Log the name of the selected cipher suite after a successful TLS negotiation. This makes it possible to check if an appropriate cipher suite was selected. Moreover, this log message is a good indicator of a successful TLS handshake.
  • Added documentation about the steps necessary for the simplest working TLS configuration. The default status of TLS support is changed: now TLS is disabled by default. This is an incompatible change! TLS should not be enabled without explicit consent, because it requires a considerable amount of configuration. An enabled TLS without a configured JSSE causes that some mails will not be delivered.
  • Issue 42
  • Issue 32
  • Issue 34
  • bugfix: avoid logging of socket close twice
  • Upgrade mail.jar. The old version has a bug affecting unit tests, it added an unnecessary line end to mail bodies.
  • Revision 417 fixes tests
  • unexpected errors are logged in the server socket thread; external interrupts are ignored
  • Now the handler is not required to consume all mail content bytes. This was intended already, but the code did not really allowed it.
  • A method is added to make easier the wrapping of existing SMTP command objects by code outside of SubEthaSMTP.

3.1.5 - February 28, 2011

  • Issue 36: PlainAuthenticationHandlerFactory should accept non-null authorization identity. Patch is provided by Ian White.
  • Issue 35: Addition of Received headers is configurable. Patch is provided by rwiermer.
  • Issue 30: Client timeouts if the server does not respond
  • Wiser.messages is now protected so subclasses can override

3.1.4 - June 1, 2010

  • Added the ability to drop connections by throwing a DropConnectionException
  • RejectException is now a RuntimeException NOTE this might be a breaking change for your app
  • TLS can be disabled
  • Publicly reported name of server can be controlled with a "softwareName" property

3.1.3 - February 11, 2010

3.1.2 - October 24, 2009

  • Announce TLS support patch
  • small optimization for getAuthenticationMechanisms()
  • catch exceptions so that all the shutdown methods get called if there is an error.
  • Default MessageHandler implementation easily extendable or replaceable

  • Fixed missing space char in extended HELO AUTH string
  • Will prevent an SLF4J error on startup by linking the jdk14 logging facility

2.0 - October 26, 2007

  • Use Apache Mina 1.1.3 for the networking layer. This make us Native IO (NIO) based. woot!
  • Expose Mina JMX monitoring.
  • Use slf4j instead of log4j for logging.
  • Rewrite build system to be easier / cleaner / faster.
  • Remove Maven pom.xml crap. Its a pile of dog shit. Don't ever use it.

1.2.1 - June 28, 2007

  • Fix issue with requiring a HELO/EHLO after a RSET.
  • Fix issue with canceling the sending of a message and not resetting internal state.
  • Add more unit tests.

1.2 - March 1, 2007

  • Integrate retroweaver into the ant build system for JDK 1.4 compatibility.
  • Change the license from LGPL to ASFL 2.0 to allow for wider adoption.
  • New feature: Pluggable SMTP AUTH and related unit tests. Thanks Marco.
  • Bug fix: Accept 'MAIL FROM: <>' and properly reject 'MAIL FROM:'. Thanks to the report from David Haggerty.

1.1 - Oct 5, 2006

  • Added new interface for instantiating the server (MessageHandler/MessageHandlerFactory). This allows much more control over the message handling. MessageListenerAdapter has been added as a backwards compatible way of creating the server instance.
  • Removed SMTPServer.setDataDeferredSize() method. This is a non backwards compatible change, but we assume not many people were using it anyway. It's possible to still modify this setting by instantiating your own SMTPServer instance and passing the value into MessageListenerAdapter or your own MessageHandlerFactory.
  • Rewrote unit tests to use a lightweight telnet client.
  • Fixed some threading issues with fast start/stop'ing of the server.
  • Added code to explicitly close any open Socket connections when the server is shut down.
