I’ve marked one email as a spam and since then I cannot receive any mail from this address. I’m trying to find out where and how I could fix my stupid mistake but no success and my despair is growing.
Would somebody mind to give me a hint where and what I have to do?
Sender is public news server where I have an account. This spam blockage is for the one account on the server. The other accounts can receive emails from this news server without any issues.
Thank you in advance.
