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