      Hi,
      While I can login into my myname@vivaldi.net account, I CANNOT send any e-mail message, nor from my IMAP desktop e-mail client (which is Vivaldi Browser, BTW(!)), nor from the web interface "webmail.vivaldi.net".

      When I press "Send" in the web interface on webmail.vivaldi.net, a red pop-up window appears, saying: "SMTP Error (554): failed to add recipient "destinationmail@whatever.com" (5.7.1 myname@vivaldi.net: Sender address rejected: Access denied)."

      How is it possible that my own access to vivaldi SMTP server is denied, while I am logged in, into webmail.vivaldi.net?(!)

      Why can't I send e-mail messages, anymore?

      Can anybody help me?

        @newscpq Are you trying to use an alias?

            @newscpq Is your recipient a user of an MS email address such as outlook.com or hotmail?
