ich habe das Problem, dass auf meinem Server mehrere Domains hinterlegt sind.
Als Hauptdomain (auf diese läuft auch der Server nutze ich domain1.de).
Ich habe Postfix so konfiguriert, dass per Postfixadmin mehrer Domains verwaltet werden können. Hier nutze ich auch Domain2.de.
Schicke ich eine Mail von Extern an markus@domain1.de funktioniert dies wunderbar.
Von Extern an markus@domain2.de funktioniert nicht.
Intern von markus@domain1.de an markus@domain2.de gibt es keine Probleme, auch umgekehrt funktioniert es wunderbar.
Genauso erreiche Mails von markus@domain1.de und markus@domain2.de auch externe Adressen.
