Although there are rules that select the details for blacklisting (such as only the domain instead of the entire emaiil address which hackers change every time), these do not work.
Blacklisting on eMclient is POOR.
So, how do we set up the blacklist so ONLY the domain counts?
If the message has already been read on another device, or moved by the server, then eM Client’s Blacklist Rule will not affect it. The Rule only applies automatically to new messages as they arrive in your Inbox.
