Re: Scalable Mail solution with NAS

Unlink the directory, and do a background fsck every few hours? :) I don't know why you'd want to do the above, but you could add code to the deliver agents; When inbound email hits the system: create the require directories and files if required, this could be mail.local, deliver or something similar. When mailbox is emptied get the delivery agent [could be pop3d or imapd] to delete any empty directories, then growing directories can be kept under control. > > The trouble with the above format is that you're ignoring any locality > that exists in the filesystem.

Agreed, but depending on the scale you'd most likely want logging file systems otherwise reboots could be painful. Regards, Neil.
