I designed it to be modular, the various components can be placed on different systems with no configuration changes required, should it be necessary. I'll note that Postfix does not appear to have any problems writing the files to its queue as fast as they are being delivered to it. Postfix and Dovecot are writing to different disks, though both are on the SAN, and both have noatime set. -Chad

I would not configure the system this way. Kind Regards, Christian -- No signature available. -------------- next part -------------- A non-text attachment was scrubbed...
