Now that I am once again messing with my own mail server I need some sort of backup in case my server at home goes down. I used to use DynDNS’s MailHop Backup MX service. It was great. If I lost my server, they would act as my backup mail server and redirect my mail to me when my box came back online.
DynDNS now has a service that will allow me to create alias’ and direct mail from my domain to any mailbox. So my mail mail domain can redirect to any other domain and mailbox I want, or to my gmail account, etc. This is great if I have/want to change my mail setup quickly, or direct mail to different systems. The concept is probably overkill for what I need, but I wanted to give it a try. I needed some sort of mail backup anyway so it was worth the price I paid.
I have been a happy user of DynDNS’s Custom DNS service for almost 2 years. I am a huge fan, they have a good solid track record for me!
