sean Great, thanks Sean for the quick response. I actually just sent a test message and saw the DKIM signature as:
Which shows the domain is dkim as you say (
s=dkim) - great!
This works for me, but I see the generic name
dkim could potentially collide with other providers if they use the same name. It's probably a big ask, but for future-proofing, it might be worth using something more unique like
opalstack or something.
