Sending Internet mails with different sender(!) e-mail adresses.

[Gruber Erich F. VASL/FAF]

Hi, who can help me.
I send Internet mails (SMTP) with the method "SendTaskDescription" of the
object "SELFITEM" (like dokumented and used in the SAP-task  TS30000102 of
WS30000015).
It works well.
 
But i have one problem:
The adress of the sender of the e-mail is always the same, namely the
Internet mail (SMTP) address of the RFC-Workflow-User in SAP (which is the
creator for batch-workitems).
 
But now i have different applikations and i have to give the mail-receiver
the possibility to send back (= to answer) to the correct official in charge
and not to a workflowadministrator.
 
Has anybody an idea, how to make variable the sender Internet adress (at
best with a container element)?
 
Is it possible to customize the object "SELFITEM"? I tried, but i did not
succeed.
 
thank you in advance:
