    Hallo,

    >> MS> a) Was schreibt Postfix denn ins log?
    >> Gute Frage, hab ich noch nicht gesehen, irgendwie habe ich das Gefühl

    MS> Na, da kommen wir dem Problem doch schon einmal naeher.

    >> MS> b) Wie uebergibt fetchmail die mails an postfix? (i.e. sendmail -t oder nicht)
    >> Wo finde ich dass denn ?

    MS> Kann fetchmail in ein Logfile schreiben? Falls ja, was steht drin?
    MS> Falls nein, starte es mit "strace -o logfile fetchmail parameter",
    MS> dann kannst Du im logfile *vieles*nachlesen.
    So habe ich nu gemacht. Also den Logs nach zu urteilen scheint postfix
    doch von fetchmail verwendet zu werden.

    Hier ein Schnippsel aus '/var/log/maillog':

    Ich hoffe nur das postfix nicht irgendwas an die Leute rausgeschickt
    hat.

    Ich frage mich, woran postfix erkennen kann das die mails einer
    Mailingliste tatsächlich für mich bestimmt sind.

    bis dann
