Probably lot of members in the past pressed on SPAM-button. SO this site's email-adres is on SPAM-list from Gmail. :spam:
But I've found the trick.
I've put the emailadres "
[email protected]" in my "contact"-list.
Reading Gmails-Help is explaning that this email-address is now not seen as SPAM anymore. :nana:
Now it's possible to change emailadres and confirm the reverification-email !
