I think I've narrowed down the problem to our local ERP system (the
originator of the emails). I believe the problem was the length of the
email address. The addresses I tested that failed were both >30
characters. I've now tested 2 addresses of <25 characters, and those have
both worked fine. I don't have visibility from the ERP to see what it's
passing, but I'm guessing it's truncating addresses.
