You probably want your email operated by professionals. Beyond initial setup and maintenance, you'll likely spend many hours setting up spam filters and pulling your hair out in the process. Unless your business is computer technology, and you work with *nix systems daily, I'd probably avoid trying to host your own mail. Your mention of CentOS shows poor knowledge of current Linux distributions and their limitations, and points to the fact you are planning on renting a Colo'd box or VPS. The latest version of CentOS, 5.5, ships with Postfix 2.3.3, which is so old it is no longer supported. The version of Dovecot CentOS ships with is also equally old and no longer supported. This is true of most CentOS packages. Did I mention the Linux kernel in CentOS 5.5 is almost 5 years old? If this is a rented box/VPS, and you are not allowed to install newer versions of the software, you will likely be instantly screwed. I'd follow others' suggestions and use Google or another hosted mail provider, and whatever VPS for web. Also note that many receivers won't want to accept direct smtp connections from VPS land. -- Stan
