1. In a half year now, I have had a 100 % filter on my Hotmail account. That is I blocked, deleted and automatically reported all emails that were not on my contacts list and on my safe list. Now 99.5 % of all spam has disappeared. This account will be closed again if spam increases. Done in a minute.
2. I also have an open email account that got a lot of spam. Now I have forwarded that to my Gmail account, and 99.5 % of the spam are filtered to the spam box. Google has an excellent spam filter. Do you filter PayPal messages on your account?
3. Now, since two hosters (as expected / predicted when I stared with sites) are also eliminated it is time to set up accounts email@example.com etc.
4. Thank you America, thank you Google and Microsoft.
Do not combine PayPal with an open account.
