Syntax Validation

Whilst this crate is not intended to provide syntax validation, some validation has been added as of Version 0.3.0.
If you are looking to validate your SPF record. I would suggest you use one of the following:

1. VamSoft.com
2. Spf-Record.com

I am sure there are many others that could be found.
