transport agent doesn't work after Exchange2007 SP1 installation   

Dear all,

the following code worked OK before SP1 installation:

void SRoutingAgent_OnRoutedMessage(RoutedMessageEventSource source, 
QueuedMessageEventArgs e)
{

....

                                         Header replyToHeader = null;
                                            try { replyToHeader = 
Hdrs.FindFirst(HeaderId.ReplyTo); } catch { }
                                            if (null != replyToHeader)
                                            {
                                                // create a recipient based 
on Display-To
                                                MimeRecipient mmR = null;
                                                try { mmR = new 
MimeRecipient(sd, s); } catch { }
                                                if (null != mmR)
                                                {
                                                    try
                                                    {
                                                        //delete old 
Reply-To:
                                                        Hdrs.RemoveAll(HeaderId.ReplyTo);
                                                        //change Reply-To: 
header
                                                        replyToHeader.RemoveAll();
                                                        replyToHeader.AppendChild(mmR);
                                                        //create new 
Reply-To: header
                                                        Hdrs.AppendChild(replyToHeader);
                                                    }
                                                    catch {...}
                                                }
                                            }


...

}

It doesn't work on Exchange 2007 SP1.

Reply-To header remains unchanged. Why? Please help.

Thanks in advance,
