Catch-All seit Jahren eingerichtet, aber Empfang nur noch an Alias-Adressen

Servus,

seit dem 22.07. erhalte ich keine Emails über die CatchAll Funktion mehr, es sei denn ich habe dafür zuvor ein Alias angelegt.
Zuvor kamen diese problemlos als CatchAll Funktion auch bei nicht angelegten Emails an.

Wenn ich mir selbst eine E-Mail zusende, dann bounct diese mit einer Meldung wie dieser:
