Seit einigen Stunden steht der ganze Mailserver. Die Queue füllt sich (sobald man den Dienst wieder startet) innerhalb weniger Sekunden auf über tausende Nachrichten und der Maillog hat auch schon die 5GB erreicht. Im Moment weiß ich nicht genau was falsch gelaufen ist.
Ich kann im Moment nur sagen, dass alle Postfächer mit "Undelivered Mail Returned to Sender" - Nachrichten überfluten werden.
Der Absender ist: MAILER-DAEMON@xy (Mail Delivery System) <MAILER-DAEMON@xy (Mail Delivery System)>
xy steht hierbei für meinen Host.
