If you ever decide to put the mail information in LDAP, then
'Whatever random piece of crap you have lying around' will be
WAY to small. I run my LDAP/Kerberos on a Sun Blade 1000 (2x750MHz
Ultra SPARC III), a Sun Ultra 10 (1x360MHz Ultra SPARC IIi) and a
Sun Ultra 1 (1x170MHZ Ultra SPARC I). This IS that 'random piece of
crap'. All three works as mailservers (forwards to the SB1k where
people get there mail - IMAP/POP) and as LDAP/Kerberos servers.

They are WAY to slow, although now they are fast enough to withstand
the pressure without crashing (I upgraded the U1 from a SS20 and that
combo crashed every now and then).


Note though the 'random piece of crap' note is true when it comes
to KERBEROS (that doesn't need ANYTHING regarding power/storage/speed)
but not LDAP... That is a lot more demanding...


But buying the cheapest machine you can find (lots of memory just to
be sure though - 1Gb) would last you quite a while. No need for SCSI
and/or SATA and all that. IDE will be fast enough (but I'd software
RAID two or more just to be on the _safe_ side).
