I'm forwarding my outgoing messages from my Exchange server through my C150. I have an Intrusion Detection appliance on my network that will drop the connection on any e-mails with a double-dot attachment (eg. file.doc.doc). The C150 sees the connection as being aborted. Consequently attempts are made to resend the message over and over again over the next few days. Is the message in a queue on the C150 and being resent from there or is it being resent each time from my Exchange server? If it is being resent from the C150, how can I identify the message and remove it from the queue. Hope this all made sense.
