Hi, our R&D department wants to register @gmx.come's mailbox for testing in response to this problem, can you help us provide the registered URL?
The next is our three-day holiday. I am sorry that we will not be able to answer the information in time.
Many regards Demi
Hi Demi
this behaviour is the same for all kind of mail adresses / email domains.
Just did a test for a fake gmail adress - country code is being added (49-...@gmail.com)
see screenshots
