If your users lack clue enough to configure
a mail client that is what support helpdesks
are for or a well structured support website.
Your talking in terms of a very large isp.
I am talking in terms of what the original
poster (who seems to be running a small to
medium mail server) can/should do. Having 2
disparate mail servers is not uncommon, I was
also thinking of a colo-swap with another
provider, its way cheaper then having to pay
loop+bandwisdth commit on a link that you only
want for backup mail servers.
It all realy boils down to what level of service
and redundancy you are looking to get to. Again I
was thinking on the cheap and less complicated because
I interpreted that is what the original poster was
looking to do =)
