I'm not sure if I'm at the right place so sorry if this is annoying
I run a cyrus mail server here at Cytopia supporting about 35 users. I
have recently purchased some new boxes to upgrade the servers. I am
upgrading the Cyrus server, but I am also keen to run a mirror backup
cyrus server. Now my question is, can anyone give me any pointers on
how to go about designing a backup mail server.
I have configured one box as I want, then mirrored in onto another. But
I am confused about the DNS setup .. should I create an alias ie mail
that can point to either??
And secondly I am keen to somehow have the mail server polled and if it
stops responding bring the backup server into play. To keep them
syncronised I am planning to use rsync... but then how do I keep the
sasl backend in sync, with different realms etc?
Anyway as you might have gathered I am by no means on top of the problem
so any ideas will be greatly appreciated.
