"lost connection" means the tcp connection failed. Don't bother with the debug_peer_list; it's unlikely to help with this. You can try capturing a tcpdump of the session. Most likely it will show the connection was lost and not much else. http://www.postfix.org/DEBUG_README.html#sniffer It might be more interesting to get a tcp recording on the other end, if that's possible. Does your offshore unit have a otherwise stable internet connection? Is this a wired connection or some kind of wireless or satellite? -- Noel Jones
