Despite clicking move to inbox and remove blacklisted domain, they keep going back to junk
It can be caused by eM Client moving the messages if you have previously blacklisted the sender or their domain. If that is the case, go to Menu > Settings > Mail > Blacklist > Manage Blacklist. See if the sender’s address or domain is in the list and remove it.
If you have removed the address or domain from the Blacklist, and it is still happening, then probably it is your server, so you will need to login to their webmail interface, select the message in spam, and mark it as not spam. Some providers have an option to whitelist senders so check on that also. Thereafter the server should always leave messages from that sender in the Inbox.
