I'm just curious what reasons, and they may be myriad, explain why SMTP will route around the damage using the MX priority, but TCP/IP won't? Ie, I can send mail where I can't send a packet?
Thanks for all the feedback, and I even found my own example, right here. I've been connected with ADSL and Wi-Fi to different ISPs and when either is down, there is no re-routing, but the two servers can still see each other across the LAN, so a secondary MX pointing to the other of the external IPs is useful, whether it points to, effectively, different machines or not (incoming port mapping).
