Unless the machine in question is a server, 200MB for /var should
be more than enough. If it is filling up often, something
is wrong (most likely there is some misconfigured software running
on your system). And if /var is filling up every day, then
/usr will fill up in five or six days given the partition sizes
you mentioned above.

Anyway, here's the procedure I use to do this kind of thing:

% cp -a /var /usr/new_var
# Reboot your machine in single-user mode. This is somewhat
# distribution-dependent, I think.
% umount /var   # May fail, don't worry about it.
% rmdir /var
% ln -s /usr/new_var /var

Again, let me emphasize that I don't recommend that you do this!

I'm sure that kind of thing is controllable, but I have not configured
any mail daemon in a long time, so I can't tell you how to do it.
