Hi. Do someone out there make use of courier to build an Active/Active Load Balancing incoming/outgoing mail clustered environment? What happens if I run two or more courier nodes in parallel within a clustered filesystem mount point (ex /opt/courier... with courier installation, configuration data, and maildirs) for incoming and outgoing mails? It is safe or I have a risk to corrupt control files and data files, or to have problems with fs sockets and ux named pipes or other courier stuff? What is the correct way (if there is any) to run courier such way?
The $localstatedir directory (/usr/lib/courier/var, or /var/run/courier), where the mail queue and other runtime files are, cannot be shared. It can be a symlink to a local dist. Everything else can be shared, however you must be aware of the results when multiple instances of Courier think they have the same identity, unless you make 'me', 'locals', 'hosteddomains*', and perhaps a handful of other control files, also symlinks to local files.
