Ok!

But still there is broken links to pictures in newsletters from DNN. It's working great with the built-in newsletter in DNN but not with Advanced Email Manager 2.6.

Switching to the FreeTextBox everything works just fine. But CuteEditor doesn't.

To reconstruct the error:

DNN3.0.13

Advanced Email manager 2.6 (EM)

 

Create a newsletter, put an image in the letter from your site. Send the newsletter and check in your outlook. Now the picture is missing!

 

So, any suggestions? Could it depend on the EM-module? Then it should not work with the FreeTextBox!?!?
