The fix for this issue changes the way that language files are loaded. While they remain in the same PHP-like format, they are processed as plain text, and any code in them will not be run, including operations such as concatenation using the . operator.
Deprecation The current translation file format using PHP arrays is now deprecated; the next major version will introduce a new format.
The fix for this issue includes a minor BC break: callables injected into validateAddress, or indirectly through the $validator class property, may no longer be simple strings. If you want to inject your own validator, provide a closure instead of a function name.
Haraka message ID strings are now recognised
