I have tried to block a specific domain .existedatnow.com
from spamming my email account. I get 10 - 20 emails a day from them with various @xys, or @xyz, or @xy? with the .existedatnow.com appendage.
Frustrating because I have used the sweep function to ask that all these immediately be deleted. And I do have to monitor my junk account to sift for things I want.
How do I block these guys?
