I was using the SDK to work with inbound CRM email this afternoon and I noticed something interesting with the email.sender field.

It contains both the display name AND the email address, as you can see below:

"Administrator" Administrator@mycrmcompany.com

While ordinarily this would not be a problem, it certainly is if you are expecting only the email address.

I'm not sure if the other email-related fields are similar, but I would bet they are.
