Google's GMail is very well known. If you use GMail, you will get a example@gmail.com email address. You would not want to use this mail if you have your own domain.

Fortunately, Google provides free powerful and reliable email server that you can use to host all of your domains' emails. What you need is a Google Apps account.

To do that, follow these steps:

• Create a new Google Apps account
  - Open this webpage http://www.google.com/apps/intl/en/group/index.html
  - Click Get Started button.
  - Fill in your domain name
  - Fill in your profile. Then click Continue button
  - Create your primary email account
• Domain verification
  Now you have to verify that you own the domain name. Click on the Activate Google Apps button on the Google Apps Dashboard. You would then have to upload a html file with a specific code, or change a field in the dns record. Do that and click the verify link to have Google verify that you own the domain name.
• Google Mail Activation
  Back to the Dashboard, click the link that says Activate email under Email section. As you click this link, you will find a brief instruction to set up your MX records. This page also provides has detailed instructions how to do this for a number of domain name providers and hosting companies. Basically, what you need to do are:

  • Delete any existing MX records before entering new MX records.
  • For each MX record, enter information according to the entries in the following table.
    You may not be allowed to enter the priority values exactly as they appear in the table below; in that case, simply ensure that the server addresses are prioritized in the same order as they appear in the table. (i.e. The priority ranking [1, 3, 3, 5, 5, 5, 5] should work just as well as [1, 5, 5, 10, 10, 10, 10] so long as you keep the addresses in the right order.)
    If you're asked to specify the type of each record you're adding, enter "MX".
    MX records often require the specific format of DNS records, including a trailing dot (".") at the end of any full-qualified domain names (e.g. "server.example.com.")
    Set any TTL values to the maximum allowed.
    MX Server address        Priority
    ASPMX.L.GOOGLE.COM.      10
    ALT1.ASPMX.L.GOOGLE.COM. 20
    ALT2.ASPMX.L.GOOGLE.COM. 20
    ASPMX2.GOOGLEMAIL.COM.  30
    ASPMX3.GOOGLEMAIL.COM.  30
    ASPMX4.GOOGLEMAIL.COM.  30
    ASPMX5.GOOGLEMAIL.COM.  30
