The rc script seems to be written to only allow for one additional
swapfile.  It should be trivial to rewrite to handle multiple files

This diff should apply to /etc/rc.d/addswap to make your setup work.

Keep a copy of the original addswap somewhere!  You will need to specify
both swapfiles in the same declaration:

swapfile="/mailstore/swap1 /mailstore/swap2"

I have only done very basic testing, but it seems to work as you'd
expect.  However, I hereby disclaim any liability...  ;-)
