Hallo zusammen,
ich habe einen VSERVER bei Server 4 you gemietet.

Beim versenden von Mails habe ich fogendes Problem: EMails die größer sind als 10 MB und sämtliche Dateianhänge werden blockiert. So viel ich weiss läuft Postfix, Spamassassin und Clamav auf dem Server. Meine Frage ist jetzt:

Wo befinden sich und wie heissen die Konfigurationsdateien der Programme wo ich die o.g. Parameter einstellen kann ?

Danke für eure Tips.

Axel

in email presumably from you (<webmaster@scbayer05.de>), to the following recipient:

Our internal reference code for your message is 17884-07.

Delivery of the email was stopped!

The message has been blocked because it contains a component (as a MIME part or nested within) with declared name or MIME type or contents type violating our access policy.

To transfer contents that may be considered risky or unwanted by site policies, or simply too large for mailing, please consider publishing your content on the web, and only sending an URL of the document to the recipient.

Depending on the recipient and sender site policies, with a little effort it might still be possible to send any contents (including
viruses) using one of the following methods:

- encrypted using pgp, gpg or other encryption methods;

- wrapped in a password-protected or scrambled container or archive
(e.g.: zip -e, arj -g, arc g, rar -p, or other methods)

Note that if the contents is not intended to be secret, the encryption key or password may be included in the same message for recipient's convenience.

We are sorry for inconvenience if the contents was not malicious.

The purpose of these restrictions is to cut the most common propagation methods used by viruses and other malware. These often exploit automatic mechanisms and security holes in certain mail readers (Microsoft mail readers and browsers are a common and easy target). By requiring an explicit and decisive action from the recipient to decode mail, the dangers of automatic malware propagation is largely reduced.

Bezüglich der ersten Fehlermeldung (size limit) dürfte folgender Parameter unter /etc/postfix/main.cf interessant sein:
message_size_limit =

soweit ich mich entsinne gilt ein Standardwert von 10 MB, falls der Wert nicht explizit in der main.cf angegeben ist.
 
Das banned contents kommt iirc von amavis. Dort sind ausführbare Dateien standardmäßig verboten.
 
Das geht nicht darum, das zip-Files geperrt sind, sondern, dass er in dem Archiv eine exe-Datei findet. Musst also nur in der Amavis-config exe Files erlauben.
 
Super Link. Hat mir sehr geholfen für meine E-Mail Einstellungen.
Habe mich nämlich bei main.cf und clamd.conf zu tote gesucht.

Danke
