What about when the gateway that goes down also handles the POP3 accounts?
I know about the only way to provide a secondary lookup for a POP3 server
is via DNS somehow,  and this could have way too much lag time.

I was thinking about this then I thought about having users setup 2
identical accounts in LookOut Express, except they go to different servers
on different networks.

So if mail ends up on MX1 it stays there for pickup, and if it ends up on
MX2 it stays there for pickup.    If MX1 or MX2 goes down then users will
still get their mail,  they will just get a warning messages about which
host is down.      A little user training would have to be done.

Any thoughts or chinks in my armor or does someone have a better plan?
