Would you like help in danish or english?
Have you tried to check if your e-mail actually works, have you tested the settings in Outlook?
If you use domain.com, have you made the e-mail from the e-mail function panel?
Do they provide e-mail systems?
(i used to be with another company, and closed my business with them as i werent allowed to have the serversettings altered for an online e-mail function.
Feel free to contact me, ill try to help out.
