And I'm not a salesman :-) But with such a setup you've got to cope with *some* spam, that's correct. What you should not do is to accept a mail for forwarding to another system you don't control (or are somewhat related to): that system could very well reject that mail, and now you have a problem. This would be what's called an "open relay". In these times, better not do that.
