Blacklisting an email address

Unfortunately it is possible that eMC does not have native capability to solve your issue.
Perhaps a better solution would be to block spoof on your mail server.
However, if any part of the spoof address is always the same the same you can try in eMC:
Menu ->Rules ->Blacklist ->Edit ->Contains
The drop down is top left of pop up Rules window:

It is the address in the From: header. But you can enter it manually following @skybat’s instructions instead, as that method is more configurable.
