[Postfixbuch-users] offenes Relay

[Klaus Schuehler]

Hallo,

wie kann ich meinen Mailserver auf ein offenes Relay überprüfen.

Habe eine Mail gefunden die meinen Server nutzt.

Return-Path: <akrnqfnxb at wongfaye.com>

Den User Riley Ferreira at zero.ksnetwork.net gibt es nicht.

Wie kann das sein.

Habe sasl Installiert. Funktioniert auch. Wie kann der meinen Server
nutzen.

Viele Grüsse Klaus
