How does your 'message queue overflow' show up? I had some kind of freezing with enabled life AV-protection, solved it by using an buffered filestream for attachments, and I use a home-grown throttle which calls MsgWaitForMultipleObject very rarely, just often enough to fake taskmanager ;-) > I know that ICS itself isn't > such bottleneck here, probably I could get it working better with that > message-parsing code put into a separate thread.
