I have several domains, all of those domains have associated e-mail addresses. Some of these e-mails have the same prefix. Currently most of them are forwarded, some have mailboxes.
I knew about Google Apps, I had even played around with it before. Although it seemed like a good product, I wasn’t really interested in using it. Recently I decided when I bought another domain to use Google Apps for it instead of my own mail server. I must say I like it, I like it so much I am now transfering e-mail for several domains to Google Apps.
This will enable me to easily setup the same e-mail prefix for all domains. I just point the domains DNS records MX part to Google’s MX servers and that’s it all domain mail will now go to Google Apps. Google Apps doesn’t only provide Gmail with you own domain, it also provides many other services. You can use Groups, Docs, Gtalk, Google Calendar and many more.
There is a free Google Apps version that will allow you to have up to 50 e-mail account with 7GB each. This should be enough for most, but if you need more you can always get the business solution they offer. It will cost you $50 a year per user, you will get 25GB space per user. The also offer additional apps. for business users. Like Google Video for Business, Google Groups for Business, BlackBerry and Microsoft Outlook interoperability and much more.
