Can workflows be triggered by user emails?

Hi,

 Can FIM 2010 R2 be integrated with Exchange to do the following:

1. User A@Contoso.com email comes into an Exchange mailbox (reset@company.com)
2. The email triggers a workflow to randomise the password for A@contoso.com and email this password touser's alternative account

What's the best way to achieve this, if possible with FIM?

Thanks
