Guys, i would like to understand the above said a little better and hence the following questions;
1. Since postfix has a mailbox_size_limit, why do we still need to have quota implemented (say via dovecot). Is it just for "enforcment and notification"? 1a. Is it ok to just set mailbox_size_limit=0 and then impose quota via dovecot (say 1GB) or must both settings match? 2. For a setup of about 1500 virtual users on a centos 5.2 machine with a raid10 array and with 8gb of ram, what settings do i need to change in postfix for better performance with regards to main.cf /master.cf. Dovecot provides POP/IMAP services. Thnx.
