This is what I do. But another thing to bear in mind is what happens if you have a problem with your home internet connection or with the computer receiving your email? Yes, email senders will retry for a while, but personally I've had my ADSL line go down for a week or more. Also, if you are away on holiday you won't be there to fix a broken email server. For most people, email service is pretty critical so you will likely want a second fallback email server somewhere else. This is what I do, I used to have a VPS for this but to save money I recently moved to an email hosting service that supports receiving emails for other domains. -- Tixy
