SMTP Integration - Missing from headers

I’m getting this error in the SMTP Send Mail piece.

Message failed: 551 5.7.1 Missing from headers

From what I can see there is nothing I can do will add message headers. Anyway this could be updated?

Turns out the from field needed to be an email and not a name, even after entering the email in the smtp set up. :roll_eyes:

All is well
