Hi. I've got a couple of persistent, not-quite-spam senders who hit my server -- the sending address is email@example.com; they do not honor the Unsubscribe link in the footer of their frequent and unwelcome messages. So I would like to just block all incoming messages from @maec.org.
I have blocked domain "maec.org" in Security | Advanced | SMTP Blocking. But messages from @maec.org still sail through to my inbox. Is there any other way I can block domain "maec.org"? There are other domains I would like to block, too. =)
Thank you as always.
