Having been at the wrong end of this, remember it's better
to
overkill the hardware than to underestimate it. Normal
load, it
should be overkill, but there are always spikes of traffic
that you
want a good amount of spare power to handle.
Keep in mind, however, another way to handle Maia is to
spread the
job out horizontally - You can have $A postfix boxes sending
mail to
$B amavisd-maia boxes, and $C web servers, plus a central
database
server. The database server is where you don't want to
scrimp on
disk IO and RAM. This is the growth route I've usually
taken -
watching the load grow and adding more muscle where it's
needed.
