So what exactly could be the cause?
I've been messing a bit with my settings, and sometimes the e-mail for activation got through --> after rebooting Postfix most of the times.
The "f-" parameter is only if things are set by default, I changed it to SMTP. Sending out by default does not work.
I've allowed the port used in the firewall as well. I really don't understand the problem.
It's a bit frustrating to see how I actually can send out e-mails but that the activation e-mails are not working.
I got new errors through testing:

Hopefully you could tell me what is wrong and how I could fix this issue.
Many thanks in advance.
