In the headers below, Smartermail doesn't stamp the SPF on it - It should stamp it whether its (Fail, none, pass, etc) 

 

You can see they do have an SPF Record. 

 

 

This is not a one time occurrence - It happens a lot.  Their seems to be something in certain emails that causes Smartermail to not stamp the email correctly. 

 

I'm running version: Version 13.3.5535

 

I bolded the line below that has the smartermail results.
