I found ages ago that setting up a mail server isn't super hard. What was difficult keeping it running reliably. Every time I would go on a trip, I'd worry that it would break down and I wouldn't be able to fix it. And I always worried that it was rejecting or spam-filtering mail that was important.

I'm not sure if this would work in practice, but wouldn't it be a possibility to forward any rejected emails to a gmail account?
