I was speaking with someone about Postfix and they suggested I use "virtual" mailboxes rather than system accounts for mailboxes. They indicated there is no point in utilzing UID's for mailusers and system accounts simply for Postfix however there appears to be hundreds / thousands of available UID / GID in the pool. Do you guys / girls see a benefit in this methodology or even understand the theory mentioned? I have only 300 users on my server and they all have their own /home/user directory w/ Maildir style Inboxes. No since this is the only function of this machine (email / Postfix), they never login and all are set to /bin/nologin.
Thanks for your input / feedback / suggestions. -- Man your battle stations...
