It should be possible, based on return code to make only the recipient fail. For example, let's say the filter returns 4 (to reject this recipient). The SMTP fail code could be 471, which means only this recipient failed. However, if the filter returns 4 + 16, then the SMTP fail code could be a 5xx code, meaning that the entire transaction fails. My own thought was to allow the filter writer to specify any SMTP error code and message (perhaps in a .REJ file or some similiar method), and simply indicate to XMail by the filter return code whether to terminate mail processing for the message, or simply dump this recipient. But I suppose it will be up to Davide how he wants to handle this...
