No problem at all. We run up to 20 different instances of cyrus on some of
our machines. You just have to setup separate cyrus.conf and imapd.conf
files, separate start/stop scripts, and use the -C option on every command
The main thing I'd recommend is that you create separate instance files
/etc/cyrus-a.conf and /etc/imapd-a.conf
/etc/cyrus-b.conf and /etc/imapd-b.conf
And completely delete /etc/cyrus.conf and /etc/imapd.conf. That way if you
run "reconstruct" or any other tool on it's own, it'll complain that it
couldn't find a imapd.conf file. You have to specify the -C option, so that
you explicitly tell the command which instance you want to work with. By not
having a "default" install, this will avoids mistakes with running the wrong
One other thing you'll have to do is bind each instance to different port
numbers, or different IP addresses.
