<html><head></head><body><div style="font-family: Verdana;font-size: 12.0px;"><div>Moin,</div>
<div> </div>
<div>ich hoffe Ihr könnt mir ein wenig helfen. Ich habe hier einen Server (Debian 6) mit Postfix und Courier. Dieser hat ein paar Accounts die Mails versenden dürfen (ca. 40 Accounts). Momentan passiert es ab und zu, dass Versucht wird (leider erfolgreich) über Systemaccounts (vmail) Mails zu versenden. Ein Ändern des Passwortes bzw. das sperren des Benutzers vmail hat rein garnichts gebracht (ein Punkt, den ich mir überhaupt nicht erklären kann) ...</div>
<div> </div>
<div>Die Authentifizierung erfolg per SASL per PAM.</div>
