Recipient address rejected - but adress exists
Posted: 14 Feb 2020 15:50
Hi all,
I get the following error on one single mailaddress. Other adresses on the same domain work without problems. I double checked the address, it really exists. How to come that efa tells it doesn't exsist?
Thanks for your help.
