Wow! A lot of people offer free E-mail service to spammers, while charging their good
customers (they run an open relay). But it's unusual to find a company willing to buy
new hardware for their free spammer clients.
I'd suggest that you use the IMail "Relay for Addresses" option, along with SMTP AUTH
for anyone that won't come from a known safe IP address.

I would strongly recommend it, especially if you are going to have a number of mailing
lists. Although technically there shouldn't be a problem running many programs on one
machine, in reality the chances of problems increase for every extra program running
on the server.
