On investigation we discovered that it wasn’t actually originating with us: in fact what was happening was that viruses were sent to non-existent mailboxes, and Exchange was attaching the original message (containing the virus) to the NDR.

We’ve been blocked a couple of times by our ISP for sending viruses. It’s perfectly entitled to do this because SMTP allows servers to accept messages for relaying to other servers.
