Currently I use eggplant.mtu.net as my mail server. However sometimes my machine is down and I'd like to keep mail from bouncing. So I'd like to setup things such that if my machine is down then mail goes to another host, probably mtu.net, and gets queued up there until eggplant.mtu.net comes back up then delivers the mail. Both machines are running some flavor of Unix, right now one is OpenBSD and one is Linux. Pointers to documentation to read is very helpful. I've got a few days of vacataion to use for this :) -- Jon Schewe | http://eggplant.mtu.net/~jpschewe | jpschewe at mtu.net For I am convinced that neither death nor life, neither angels nor demons, neither the present nor the future, nor any powers, neither height nor depth, nor anything else in all creation, will be able to separate us from the love of God that is in Christ Jesus our Lord. - Romans 8:38-39
