Laurens Hello, which version of mail server?

Laurens

aaPanel_thisyear I use mail server 4.1

Laurens

aaPanel_thisyear I fixed the problem.
It's very stupid but obvious!

Dont use capitals in the email!!

I did the following:
Test@email.com

But I had to change it to:
test@email.com

Now it's working perfectly, thanks for the effort!!
