No one, in this email train, is mentioning what folder you are blocking these emails from.
Is it in your "inbox"? Is it in the "Junk" Folder?
Are you just stating that blocking them through this process removes all these unwanted spam emails from both folders? Never to see oncoming spam email again from agencia.es?
A bit more detail, I believe, is necessary from this thread for the community for stopping this spam.
Yes, I've blocked, entered the domain, flagged, reported, etc. But I'm still seeing this spam in my "Junk" Folder.
I DO NOT believe there is a clean process to rid of this spam without Microsoft's help.
In other words, this spam will be at least, in your "Junk" folder .... for years to come.
