[CentOS] Re: Planning Mail Server (with low resources)

Restructuring setup
---------------------------------
Hardware:
Pentium III 1.4Ghz
256 RAM
40 GB HD-IDE

Soft:
CentOS 4.2
Postfix
Cyrus-IMAPd

Partitioning(in MB):
/                         8.000
/boot/                  100
swap                   512
/home/                15.888
/tmp/                   500
/var/spool/imap/    15.000

would be this a candidate setup?

I'm planning use quota (as suggested in this list) on cyrus level,
giving the students the possibility of free their inbox when it is
over quota, and let the messages that are in queue (recently) get into
the inbox when the space is freed.

In the future, think the possibility of use postgresql (and some php
application) to manage users accounts.

Like the beginning, it'll be appreciated any suggestion about.
