NAME

"razor-check" - Razor Filtering Agent

CONTENTS

SYNOPSIS



    razor-check [options]  [ mail1 [ mail2 .. ] ]

    $ cat mbox | razor-check
    $ razor-check ./mbox
    $ razor-check -d mbox mail.1 mail.2 mail.3



DESCRIPTION

razor-check checks a mail against the distributed Razor Catalogue by communicating with a Razor Catalogue Server. It should be invoked before the mail is delivered or processed by a human. razor-check terminates with exit value 0 if the signature for the mail is catalogued on the server (spam) or 1 if the mail is not catalogued by the server (not a spam). razor-check should be invoked against every incoming mail by mail processors (like procmail) or MTAs (like sendmail). An alternate method would be to call razor-check from cron, at regular intervals, to identify and mark spam in queued mailboxes.

If razor-check is passed more than one mail, it will check each against the database, printing out the serial number of every mail considered to be spam. razor-check supports mbox-formatted files with 1 or more mails in them as well as files containing a single RFC 822 (non-mbox) mail. More than one file may be present on the command line, can be either a non-mbox or mbox in any order. However, more than one non-mbox mail cannot be read from stdin.

USAGE

razor-check is usually run by piping the contents of the mail to it, or by providing the name of the file that contains the mail message to be checked as the last argument. razor-check takes the following arguments:
-h Print a usage message and exit.
-v Print the version number and exit.
-d | --verbose Print debugging information.
-debuglevel=n | -dl=n Set debug level to ’n’. Default is 3 without -d option, 9 with.
-whitelist=file Specify file to use for whitelisting. Overrides ’whitelist’ option in razor-agent.conf.
-s Simulate a check. Do everything except talk to the server.
-conf=filename Specifies an alternate configuration file. If not specified, it is computed, see razor-agents(1) manpage for details. See razor-agent.conf(5) manpage for various configuration options. The default is <razorhome>/razor-agent.conf.
-home=dir Specify razorhome directory. This is where the configuration file, logfiles, identities, and server files live. If not specified, it is computed, see razor-agents(1) manpage for details.
-logfile=file Specify file to log to instead of what is in the configuration file. The default is <razorhome>/razor-agent.log.
-rs=razor.server.com Use this Razor Catalogue Server instead of reading servers.catalogue.lst.
-H Compute and print the signature of the mail contents and exit. If -e=integer is not specified, all supported engines will be used.
-S=string Accept a list of pre-computed (with -H) signatures on the command line, instead of computing one from mail content. Signatures can be submitted in hex or base64, but base64 is preferred. Requires -e=integer. Usage:

razor-report -e 1 -S a8a3d545adb73f9733675571ffeaf10cba87745b

-e=integer Specify engine used to create signatures. Must be 1, 2, 3, or 4 in this version. Engine 1, or -e=1, is used for Razor 1.x signatures. Used only with -S=string or -H.
-ep4=string String used by engine 4 when computing signatures. Published by the Razor Catalogue Servers and updated very frequently. Used only when -e=4.

RECIPES

razor-check is usually invoked from procmail(1). Here are some common ways of using it with procmail:
To change the Subject header if mail is spam:


    :0 Wc
    | razor-check
    :0 Waf
    | formail -i "Subject: Razor Warning: SPAM/UBE/UCE"



To add a X-Razor2-Warning header to spam:


    :0 Wc
    | razor-check
    :0 Waf
    | formail -A "X-Razor2-Warning: SPAM."



To file spam in a mailbox


    :0 Wc
    | razor-check
    :0 Wa
    /home/foo/Mail/razor-caught
