Kein Header-Eintrag von amavis
Ich habe viele Mais an die ML bzgl. amavisd gelesen, bin aber nicht fündig
geworden, warum ich keinen Header-Eintrag mit client4 habe.
Unten sieht man, dass amavisd gestartet wurde und auch clamav automatisch
aktualisert wurde. Statt * ist ein FQDN zu betrachten. Vom Host gw erfolgt
ein amavis-Eintrag, von client4 nicht. Mails an root und ab von client4,
werden an den User ab auf gw via /etc/aliases umgeleitet.

Das Mail wurde also offensichtlich durchgelassen.
Vom Rechner gw erhielt ich dann einen Virusalert.
Kann es sein, dass mein Postfix nicht so konfiguriert ist, wie ich möchte,
nämlich, dass der lokal sendende Client bereits auf Viren prüft? Es folgen
noch weitere Infos:
