It depends on what you want to do. For simple redirections, most domain name registrars offer this service and you can set a number of email redirections from your admin web interface on their website. I think this is all you need. If you want to do more complex things, it is quite easy to setup Postfix [1] on your own server (a little VPS would suffice) to do the redirection, even using a database like MySQL to dynamically create / update the redirections.
