FYI - check your smtp server, had to register with the google login because regular register require email verification

Hi warren
May has happened to me since I started to contribute my 2-cents of experience beginning of Sep 2020 to forum posts
All reply notifications stopped about Jan 2021
It looked like I was blacklisted for too many posts responding too much and contradicting very knowledgeable senior forum members 

Have a look if you may

Thanks
Torsten
