Every few days, SPOTIFY sends spam to one of my no-reply mailboxes. I don't know how they got it. That generates an auto response from me, saying "this box doesn't accept mail. That in turn generates a response from Spotify, saying the same thing, etc, etc. I can't contact Spotify - because all I have is a no reply address. I can't log on to my account - which they suggest - because, I don't have an account. I've blocked their domain on the server, but I guess, I'm not alone in being spammed by these guys.
