1000% overkill for only 10 users.  As an example, I (still) have a
66MHz 486 with 48MB RAM and a single 2GB SCSI drive handling over 300
users with sendmail and cyrus-imapd.  Focus on reliability foremost,
so mirror those two SCSI drives you have.  The Proliant 1850R doesn't
offer the ability to use redundant memory, but it at least does ECC.
You'll also have an extra processor already there if one happens to go
south, and you would never notice it was gone.

Consider cyrus-imapd2 or cyrus-imapd22 instead of courier-imap.  Very
reliable, very fast, and offers you the ability to create a "black
box" mail appliance that does not require the use of local user
accounts, if you wish to go that route.
