Garett noticed this new feature few days ago in the Gmail source code, a feature to manage email other than google email from Gmail interface. And today Google announced officially the Gmail for your domain hosted service. The service is beta as usual but this google is experimenting this feature for organisations such universities and colleges.

San José City College (SJCC) has embarked on a technology improvement program, and for the first time will be offering student email accounts. That’s where we come in. We’re testing a new service with the school by hosting Gmail accounts with SJCC domain addresses (like [email protected]), plus admin tools for efficient account management. Massive storage and features that tame the most unruly inboxes, like powerful mail search, conversation view for messages, and a fast interface, make Gmail very handy for students. Together, we’re pleased to provide this channel for better communications and a stronger community for all 10,000 SJCC students.


The service include 2 Gig of storage for each account with all Gmail features to help users find information fast, in addition to a control panel to easily manage user accounts, aliases and mailing lists. Gmail for your domain is currently available as a limited beta. If your organization is interested in helping Google test this service, we’ll consider your domain for this beta. You’ll need to sign in with a Google Account (or get a new one), and answer a few quick questions about your organization and your email needs.
