Syscp & Postfix Problem with SPAM - why doesn´t work it ??

Post by t-eddie »

Hello Root-Forum,

I use syscp now for nearly a year and im really happy with it....but now I also want to use the the Mailfunktion on my Rootserver, and i install postfix with the syscp howto - and everything works fine.

Now I use everyday the Mailfunktion in Postfix and i have a Problem with SPAM - so i had install ClamAV and Spamassassin with the Modules for SysCP. I use this Howto http://www.syscp.de/wiki/config/Install ... onmaildrop and also this One http://www.volkerjanzen.net/syscp/spamfilter

BUT when i logon my Emailaccount with Squirellmail - there is my Inbox full of SPAM - and the rewirte Rule with the Subject doesnt work.

And i have no Idea where i have to look, to solve the Problem - can you help, what i should check - with Log-Files i have to look??
The postfix daemon works fine, but only the SPAM-Filter doesnt work

Welche re-write rule? Du hast in Deiner spamassassin local.cf

Code: Select all

# rewrite_header Subject *****SPAM*****
# report_safe 1 
auskommentiert. Nimm das mal mit rein.
Was sagen die Header der jeweiligen Mails? Da sollte wenigstens was von Spamassassin drin stehen.

Hallo,

mhmm, wer lesen kann ist klar im vorteil.. :oops:

Ich habe die Zeilen gestern wieder mit reingenommen

Code: Select all

rewrite_header Subject *****SPAM*****
report_safe 1


und Spamassassin neugestartet, der "spamd" Prozess läuft auch - trotzdem kommen Spammail´s durch, und im Header findet sich absolut kein hinweis aus Spamassassin - was hab ich falsch gemacht???

Oder wo soll ich noch mal suchen/ nachschauen??

Aber wenn maildrop nicht laufen würde, könnte ich doch keine Mails empfangen und versenden, oder ??

Kann ich das irgendwie testen, oder in den Logs sehen - ob Maildrop die Mails überhaupt annimmt und durch die Scanner schickt ???

Hm, hast Du mal in die main.cf von postfix geschaut, ob da alles passt? Läuft der transport über maildrop und ist der in der master.cf auch korrekt gesetzt?

Irgendwie scheint ja der Mailfilter gegen Viren zu funktionieren, sonst würde die eMail in Deinem Log ja nicht zurückgewiesen. Allerdings sieht mir das nicht nach maildrop aus, weil lauft config die Virenmails ja nicht zurückgewiesen, sondern in ein Verzeichnis verschoben werden.

Poste mal die main.cf und die master.cf. Und warum muss es dann maildir sein? amavisd-new ist doch viel geiler mit Postfix :)

Mhmm, warum Maildir....ehrlich gesagt, es wurde empfohlen - von einigen die auch syscp einsetzten.

Was ist denn amavisd-new ??? Gib´s irgendwo nen gutes howto?

Ich hoffe wir finden hier irgendwo einen Ansatz, wo ich weiter suchen kann....Danke schon mal im voraus..
