Sometimes you want to customise the bounce generation. It could be anything from translating bounces into another language or making them more user-friendly, to implementing standards such as SRS. In order to do so, you’ve had to override Halon’s default bounce generation. In our new release Halon 5.4 “bouncy”, we’ve added many options to the built-in bounce generator. This enables you to quickly tailor the way bounces look and work, without having to reimplement the default generator.
Queue([
"delay" => 3600,
"dsn_delayed" => true,
"dsn" => [
"readable_mimepart" => MIME()
->setType("text/html")
->setBody("<em>choo choo train is delayed</em>")
->toString(),
"original_headers" => false,
"subject_prepend" => "Not making it in time: ",
"headers" => [
"Foo: Bar"
]
]
]);
As usual, the release comes with many other improvements. The foreign function interface (FFI), which is used for loading external libraries into the MTA executable, can now export File classes as a C++ std::istream and X.509 resources as OpenSSL pointers. This powerful feature enables you to access the (potentially modified) email body as a virtual file. We’ve also added chunking (BDAT) for both sending and receiving, a zero-fill right shift bitwise operator, a data callback to the http() function, FFI function callbacks, and much more. Please see the release notes for a complete list of changes. We hope that you will enjoy this release. If you are new to Halon, don’t hesitate to contact us if you have any questions.
