You don't even have to pay to use gmail with your own domain. I find it difficult to find the relevant links, though.

I use Apple Mail for backup. The only issue is the TTL setting for the DNS MX record. Some domain hosts set this to 24 hours, which means it may take up to 48 hours for all mails to get through after you switch to a different mail server.

but in this way you dont have support and if something is not working you have no one to complain with.. even though it seems by what i'm reading here that no one is safe, neither paid google apps users...
