for the pop3 backup thing i was actually thinking of having the backup
server run a pop3 daemon and just point DNS for the pop3 hostname to the
new server. i.e. if pop3.yourdomain.com normally resolved to a primary
x.x.x.x and x.x.x.x was down or something, you could change dns for pop3
to y.y.y.y and have that server have the password files that the main has,
or better yet, a more flexible auth method, like mysql, which is my plan.
even if they can't retrieve any mail, at least they won't know about it,
because it will auth fine and just say you have no new messages, since the
mail spools aren't there.
it's not a GREAT solution, but i suppose it's better than nothing.
here's the roadblock i found though.
if you're in, say, netscape messenger, and you check mail on
pop3.yourdomain.com, and then the primary goes down and you change your
DNS around, when said user goes to check email again, it STILL tries
x.x.x.x and not the new y.y.y.y. it caches the freakin' host->ip info.
and the only way to get it to go to y.y.y.y would be to close the browser
and re-open.
i dont know how outlook and eudora work, but that's what i found with
messenger.
