16GB seems very small. As cheap as storage is, why not get something
with enough room for now and the future? Also, a 16GB drive is surely
used, and it might not last very long.

Which list archives? Postfix keeps its queue in /var/spool/postfix by
default. Your syslogd probably uses /var/log, and yes, logging is
important.

You don't want your queue partition/filesystem filling up.
You don't want your log partition/filesystem filling up.
If you make too many separations, you might eventually find that your
hands are tied when it comes to dealing with new circumstances in the
future. Linux LVM is probably a good idea ... on a suitably large, yet
inexpensive, SATA drive. While you're at it, make it two or more
drives: SATA RAID (real hardware RAID, I mean, not in-the-driver
fakeraid or Linux software RAID) isn't awfully expensive either. 3ware
is a good choice.
I figure this: your company had the money to waste on MSexChange, so
they might as well spend enough money on this hardware. The additions
I've suggested probably cost far less than your license fee.
