I’ve not got a clue TBH about how spam filter work the other end of the line but I admit spam filters have come along way since back in the day 20 years ago I was showing a potential computer user how search engines work and how wonderful they are when I ask him to name a city or town anywhere in the World that the computer would give us everything we need to know about the town or city when he said “how about Amsterdam” and putting just “Amsterdam” into the search box brought up pictures of many naked girls in shop windows and not one canal or even a boat.
Just lucky I was not giving the demo to the Vicar or her in doors. ?
With the Opera browser I use with it’s built in VPN, I only use the VPN because my anti-virus keeps popping up saying everyone is watching me and knows where I live. ?
