Description 

Author

This class can be used to parse and decode MIME e-mail messages.

It supports decoding single RFC 2822 MIME messages or archives that aggregate multiple messages in the mbox format.

The decoded message data is returned as an array that describes one or more messages found in a message file or data string.

The bodies of multipart messages can be decoded into distinct sub-messages.

The message body data can decoded and saved to separate files, so the class can handle messages larger than the available memory.

The parser can tolerate some syntax errors in malformed messages that are not compliant with RFC 2822.

An auxiliar class is provided to parse and extract e-mail address lists from message headers.
