[MlMt] Smart box that shows emails I've sent with a question mark that have not received a response yet

[Max Rydahl Andersen]

Hey,

I was wondering if there is a way to have smart mailbox that shows 
emails I have sent with a '?' in my text that
have not yet received a response ?

Could also be filtering on something else like a "follow" tag I could 
put on email threads i'm interested in and want to get an indication if 
I have outstanding questions.

Possible ?
