I'm more than double that. Is more too many?

I'm very close to that.

Both of which are well less than what I have. What would this do?

Sounds right.

Right again.

Not yet, but it will be in time as I move more lists. I am way over
due for some upgrades and the box no longer covers what I need, so I'm
looking to move to a new server. I'm thinking a two HD box running
C-panel, and I'm looking to run a better MTA than sendmail.

Could be, but my lists are currently announcement lists that send at
a low mail time. I once let the runaway process go for 15 minutes to see
if it would clear, it did not. The open relay checks cut my mail volume
substantially, and I suspect I'd hear from some customers if I stop them.
Thanks for the help.
