Hi,

Just wonder if it's possible to run two dovecot servers on two different machines, but serve out of the same directories.

I would like to test second dovecot server before switching from first one to second one.

Any suggestions?

If you're using Maildir, this should be fairly straightforward (with all the NFS caveats - see http://wiki.dovecot.org/MailLocation/SharedDisk for a start).

I believe it's also possible with mbox - I know Timo put in a lot of time making locking work reliably with mbox.
