---|
| 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. |
