14 | * This is tnef implementation for z-push. It is based on |
---|
15 | * Zarafa's tnef implementation. |
---|
16 | * |
---|
17 | * The ZPush_tnef class does only simple reading of a tnef stream. |
---|
18 | * Most importantly, we currently only support properties within |
---|
19 | * the message itself, and do not support recipient tables and |
---|
20 | * attachment properties within the TNEF data. |
---|
21 | * |
---|
22 | * The ZPush_tnef class will accept TNEF streams with data about |
---|
23 | * recipients and attachments, but the information will be ignored. |
---|
24 | * |
---|
25 | * Created on 21.06.2008 by Manfred |
