I have created a website for a company. http://www.elmer-adv.dk
They are using local exchange server for mails.
When I sent out newsletters using Wysija it works great. I can sent to gmail, hotmail, live and so on. But I am not able to sent newsletters to their own mails e.g. email@example.com.
What to do?
Really hope you can help me because it is a big issue not to be able to sent previews to their own mail.
