With hundreds (if not thousands) of popular email clients and mail servers out there, importing email into another service can be challenge, especially when you consider the troves of old email most people save. To ease this pain, we created the Google Apps Email Migration API.
This new API is available in Google Apps Premier, Partner, and Education Editions, and you can use it to migrate your existing email from anywhere into Google Apps. Let's say, for example, you want to import email from your Obscurix Email Server v2.0001715. Just write some parsing code and use our simple API to upload that email into the desired mailbox. For convenience, you can authenticate to the API not only as the end user of the destination mailbox, but also as a Google Apps administrator, and target any mailbox in the domain. This API uses the Google data API protocol, which means there are a host of client libraries to make importing even easier.
LimitNone (one of our Enterprise Professional partners) has already built a migration utility that works with calendars, email and contacts.
