Recently, email that is not spam has been being marked as junk. I have added the senders to my contacts and removed the email from the blacklist (you might want to rethink using that word). It doesn’t matter. What has changed? What can be done to remedy this problem? This has changed over the last month or so.
Well, it depends on what is moving the messages to Junk/spam.
Normally 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.
If it is not the server it can also 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 > Privacy > Blacklist > Manage Blacklist. See if the sender’s address or domain is in the list and remove it.
Why? A blacklist is the universally accepted computing term used correctly in this case to mean a list of addresses or domains that are regarded as unwanted and should be excluded from the Inbox.
