    this iron should handle serious load without probs.

    1.) how large is your userbase?
    2.) do you know the bottleneck? (cpu, i/o, ram etc.)
    3.) average mails processed per day? (ham/spam/virus ratio?)
    4.) sendmail is slow compared to other modern unix MTA`s
    5.) procmail and spamassassin are resource hogs

    ...or multiple smaller boxes, load balanced via rrdns or a dedicated
    load balancer.
    anyway, i think hardware is not your problem...as long as i dont have
    any numbers its hard to make suggestions. im running >25k userbases on
    single self built x86 hosts (mostly p4`s (> 2ghz), 1gb ram, raid-10 (4
    hd`s) - its all about fine tuning the whole system (os, mta, other
    daemons/apps) for performance (btw. - i dont have any 5.x production
    boxes right now, im talking 4.x here).
