I have changed to email address to another name @my_domain.com, but to no avail. I only got that confirmation in my browser
Your profile has been updated, except the e-mail address. An email has been sent to your new e-mail address {another name @my_domain.com} with a special link to the profile page. Click the link on that e-mail to complete your changes.but of course, since I did not receive that email, I did not click on the link.
