Hosted CRM system with an API?

I apologize if this is slightly off-topic.

I'm hoping to find a software-as-a-service CRM system that can be easily integrated with our custom user management application. Fundamentally, we have user our own accounts and provide services to these registered users; frequently, we have email conversations with people that own these accounts - it would be great if our CRM interface would suddenly light up with the record of these conversations.

Here's my dream solution, let me know if this is possible: - We have a "service" email alias; i'd want to add the "track@GreatCrmVendor.com" to that alias so that all emails are CC'd to our CRM vendor. - In the admin UI for our app, I'd love to have access to the emails that the CRM vendor has captured for us - something like a REST-based web service call that aks "give me all email headers for customer with email X".

Do you know of such CRM vendor?

Clarification: I know how to build such a catch-all email account, parse the emails, record them in the database and all... I just don't want to invest the development time in it, I'm hoping we can just integrate with a good off-the-shelf solution.

Thanks!

  It plays well with email - AND has an API if you want to do integration...

• Salesforce.com has an extensive SOAP API for what I understand.

• There are several apps in the Salesforce AppExchange that claim to handle this:

  The salesforce.com API is also pretty straightforward to use.

• Sugar CRM has an API, and they offer a hosted service.
