Hey Bernd, (and all others)

thanks a lot for your answer. Helped me a lot!

So, the hardest part was actually the rewriting of sendmail, which does
not work quite well yet. Maybe I should switch to exim or so.

But anyway. Another question: Does anybody know good companies that
provide hosting w/ or specifically for mailman lists?
