Incomplete types for `Message`

[chriskuech]

I'm creating an Inbound Stream in Postmark. It has worked well so far, but I'm having trouble parsing To emails.

The JSON shown in the postmark app show a ToFull field that parses all the emails in the To line. This would make my job much easier; however, the Message type in postmark does not contain this ToFull field.

Please include ToFull in the Message class so we may leverage Postmark's To parsing.
