Guys,
I'm considering building a replicated mail service. If the primary goes
down for any reason (software or hardware), I need to be able to switch
over to the backup service, simply by changing the MX. Minimal mail
should therefore be lost or bounced and customers will not
inconvenienced when we try to fix a disk or whatever. Is there any
software already which will allow this to be done. I have had a quick
scan at the qmail archives, but that didn't really turn anything up. The
main issues are really "how to replicate imcoming messages" and "how to
replicate POP3 transactions", though I'm sure it's a bit more involved
than that.
Thanks for any help or advice you can give, regarding this matter.
