"outsidebox" is a machine for which I have a cert and can scp back and forth. Coming FROM there with a large file is fine. Something is very broken in the network code and I have nothing showing up in the logs or on the console. It's not sendmail -- it's the system itself. This is an embedded Intel gigabit chipset (em1) on a Supermicro motherboard and was working fine under 9.2. Ideas? This one will force me to find a way to roll back if I can't find and fix it immediately.
