Surprisingly, very few people are aware of Google Applications. Most know about Google Mail (Gmail), but did you know you can edit documents, keep a calendar, edit spreadsheets and create and publish simple web sites?

When setting my VPS server, one task was to set up and configure my mail server. A quick read of POSTFIX nearly sent me into a coma. Fortunately, an added bonus of Google apps is the ability to use them as your mail server. If you have control over your DNS you can add the settings (MX record) found in Google’s help pages and have it manage your incoming and outgoing emails.

There is a premier package, for a small amount you can be part of a service which guarantees 99% uptime. I have the basic free package and have yet (touch wood) to encounter any downtime.
