Is there an open bug report in core?

Yes.

https://github.com/openhab/openhab-core/issues/2273

^ Also to be clear: this is NOT a problem with the mail binding: – THIS IS A PROBLEM IN THE OH CORE!!

In case anyone is waiting for me to solve this: I have tried many things, without success, and I give up. => So hopefully someone else has an answer.
