Hi, I created a mail forward in ISPConfig to a eMail on the same server (also created with ISPConfig). I tried to forward it to the eMail [email protected] -> did not work. So I tried to forward it to [email protected] -> works! When I forward to an external email it also works. So why does it forward the mail correct when I use the username ([email protected]) but not when I use [email protected]? So that was the first one, now the second one... In the header is the following spam report: The IP comes from here: Is this just because my current IP (dynamic from my provider) is on a blacklist? Or is there a failure in my config? Greetings.
