/***********************************************
|
|
* File : tnefparser.php
|
|
* Project : Z-Push
|
|
* Descr : This is tnef implementation for z-push.
|
|
* It is based on Zarafa's tnef implementation.
|
|
* This class does only simple reading of a
|
|
* tnef stream. Most importantly, we currently
|
|
* only support properties within the message itself,
|
|
* and do not support recipient tables and
|
|
* attachment properties within the TNEF data.
|
|
* This class will accept TNEF streams with data about
|
|
* recipients and attachments, but the information
|
|
* will be ignored.
