[Postfixbuch-users] Interne Mails kommen nach Update nicht mehr an

[postfix_ml at rirasoft.de]

Hallo zusammen,
ich habe meine XEN-Server (CentOS 5.1) letzten Montag aktualisiert und
seitdem kommen die Statusmails der Instanzen nicht mehr an. In der
/var/log/maillog des Mailservers steht dazu folgendes drin:
Feb 20 21:08:42 mail1 postfix/smtpd[13118]: connect from

An der Postfix-Konfiguration wurde nichts geändert. Die einzigen
Änderungen sind die Updates auf die aktuellste Versionen von CentOS 5.1
