I also run WinMailDat on Win2003 server running CGP and MAPI and experience the same problems you are experiencing.

The problem is the MAPI. An easy test to prove this is shutdown Outlook and do not allow it to touch the emails at all. Run your iPhone for a few days (making sure Outlook and especially MAPI never touch these emails). Suddenly WinMailDat filter and CGP are working wonderfully for the iPhone/iTouch. Open Outlook with MAPI and then the messages are all altered by MAPI, the filter doesn't even get run when this happens and suddenly the iPhone/iTouch can no longer read the emails as they all have Winmail.dat attachments. Until they fix this problem with the MAPI client, using MAPI/Outlook and an iPhone together is a total waste of time.
