Hi,
I configured the Mailserver-settings, so that mails are created correctly. Now I wanted to create a profile to send SMS via e-mail. unfortunately, this results in the attached error. I can enter any mailadress whre the mails should be sent to. It always creates this error messages. However, if I use an internal mailadress, it works and a mail is sent to this user. But it does work with mailadresses in another domain.
