Sender based Relay problem after update to ZCS 6

[hupp]

Hi,

I have a OpenSorce ZCS 5 Installation with sender based relay (Relay per Domain - Zimbra :: Wiki) function updated to ZCS 6.

Now the sender based relay function only works if I send a testmail with telnet.
If I send a mail over the webinterface and select another Mail From address (which will be relayed) the mail will be delivered directly, because the sender isn´t right if I watch in the log file.

Anybody know this problem? Can anyone help me?

Thanks
