NAME
"razor-check" - Razor Filtering Agent
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
