Why there’s a rule about SPAM since there’s no spam filter feature in the program?
Hi, eM Client unfortunately does not have a SPAM filtering system, you can add unwanted senders or domains on your blacklist, just use the “Move to Junk” button and following options should be displayed.
After you do so, if a new unread email from the unwanted sender is received, it will be automatically moved to your junk folder.
Junk filtering is usually a server side feature, as email clients are only able to process rules when they’re online and connected to your IMAP server.
Hope this helps.
