Safe domain still cames to SPAM

I repitedly mark mail domain as safe, but it still cames to JUNK folder.

What can I do?

Normally, it is your server that is moving the messages to Junk, so you will need to login to their webmail interface, select the message in spam, and mark it as not spam. Thereafter the server should always leave messages from that sender or domain in the Inbox.

How did you “mark mail domain as safe”?
Perhaps your mail host is classifying it?
Any eM Client rules doing the “moving”?

I am just keep mark as: Move to Inbox and remove blacklisted domain

Is this an eMC rule?

Yes i suspect as @Gary wrote that your Server is more than likely moving that senders email via their own spam filtering and has to be allowed on your server filtering mailbox end which will then reflect in eM Client to stay in the Inbox.

Yes. Right click on received email.

I will talk to hosting company. Looks like it is the reason.
