Thanks for the offer Angelo
I think based on the amount of domains this is happening with along with
the fact it only happens with a very specific sending environment it's
confirmed.
But if you'd like to try, you can send an email to kenfcamp_at_campbus.com.
I'd assume Outlook via O365 would be a good place to start, but I'm only
guessing on what's being used based on the companies involved.
