16 "razor-check" checks a mail against the distributed Razor Catalogue by
17 communicating with a Razor Catalogue Server. It should be invoked
18 before the mail is delivered or processed by a human. "razor-check"
19 terminates with exit value 0 if the signature for the mail is
20 catalogued on the server (spam) or 1 if the mail is not catalogued by
21 the server (not a spam). "razor-check" should be invoked against every
22 incoming mail by mail processors (like procmail) or MTAs (like
23 sendmail). An alternate method would be to call "razor-check" from
24 cron, at regular intervals, to identify and mark spam in queued
25 mailboxes.
26
27 If "razor-check" is passed more than one mail, it will check each
28 against the database, printing out the serial number of every mail
29 considered to be spam. "razor-check" supports mbox-formatted files
30 with 1 or more mails in them as well as files containing a single RFC
31 822 (non-mbox) mail. More than one file may be present on the command
32 line, can be either a non-mbox or mbox in any order. However, more
33 than one non-mbox mail cannot be read from stdin.
34
36 "razor-check" is usually run by piping the contents of the mail to it,
37 or by providing the name of the file that contains the mail message to
38 be checked as the last argument. "razor-check" takes the following
39 arguments:
40
41 "-h"
42 Print a usage message and exit.
43
44 "-v"
45 Print the version number and exit.
46
47 "-d | --verbose"
48 Print debugging information.
49
50 "-debuglevel=n | -dl=n"
51 Set debug level to 'n'. Default is 3 without "-d" option, 9 with.
52
53 "-whitelist=file"
54 Specify file to use for whitelisting. Overrides 'whitelist' option
55 in "razor-agent.conf".
56
57 "-s"
58 Simulate a check. Do everything except talk to the server.
59
60 "-conf=filename"
61 Specifies an alternate configuration file. If not specified, it is
62 computed, see razor-agents(1) manpage for details. See
63 razor-agent.conf(5) manpage for various configuration options. The
64 default is "<razorhome>/razor-agent.conf".
65
66 "-home=dir"
67 Specify razorhome directory. This is where the configuration file,
68 logfiles, identities, and server files live. If not specified, it
69 is computed, see razor-agents(1) manpage for details.
70
71 "-logfile=file"
72 Specify file to log to instead of what is in the configuration
73 file. The default is "<razorhome>/razor-agent.log".
74
75 "-rs=razor.server.com"
76 Use this Razor Catalogue Server instead of reading
77 "servers.catalogue.lst".
78
79 "-H"
80 Compute and print the signature of the mail contents and exit. If
81 "-e=integer" is not specified, all supported engines will be used.
82
83 "-S=string"
84 Accept a list of pre-computed (with "-H") signatures on the command
85 line, instead of computing one from mail content. Signatures can be
86 submitted in hex or base64, but base64 is preferred. Requires
87 "-e=integer". Usage:
88
89 "razor-report -e 1 -S a8a3d545adb73f9733675571ffeaf10cba87745b"
90
91 "-e=integer"
92 Specify engine used to create signatures. Must be 1, 2, 3, or 4 in
93 this version. Engine 1, or "-e=1", is used for Razor 1.x
94 signatures. Used only with "-S=string" or "-H".
95
96 "-ep4=string"
97 String used by engine 4 when computing signatures. Published by the
98 Razor Catalogue Servers and updated very frequently. Used only when
99 "-e=4".
100
102 "razor-check" is usually invoked from procmail(1). Here are some common
103 ways of using it with procmail:
104
105 To change the "Subject" header if mail is spam:
106 :0 Wc
107 | razor-check
108 :0 Waf
109 | formail -i "Subject: Razor Warning: SPAM/UBE/UCE"
110
111 To add a "X-Razor2-Warning" header to spam:
112 :0 Wc
113 | razor-check
114 :0 Waf
115 | formail -A "X-Razor2-Warning: SPAM."
116
117 To file spam in a mailbox
118 :0 Wc
119 | razor-check
120 :0 Wa
121 /home/foo/Mail/razor-caught
