All mail-parsing and formatting code has been moved to em-format. Parsing is handeled by EMailParser class, formatting by EMailFormatter. Both classes have registry which hold extensions - simple classes that do actual parsing and formatting. Each supported mime-type has it's own parser and formatter extension class.

*
|
|
* When the @mime_part contains for example multipart/mixed of one RFC822 message

|
|
* parsed, returns @NULL when the parser is not able to parse the part.
