DESCRIPTION

spamassassin is a simple front-end filter for SpamAssassin.

Using the SpamAssassin rule base, it uses a wide range of heuristic tests on mail headers and body text to identify "spam", also known as unsolicited bulk email. Once identified, the mail is then tagged as spam for later filtering using the user's own mail user-agent application.

The default tagging operations that take place are detailed in "TAGGING" in spamassassin.

By default, message(s) are read in from STDIN (< mailmessage), or from specified files and directories (path ...) STDIN and files are assumed to be in file format, with a single message per file. Directories are assumed to be in a format where each file in the directory contains only one message (directories are not recursed and filenames containing whitespace or beginning with "." or "," are skipped). The options --mbox and --mbx can override the assumed format, see the appropriate OPTION information below.

Files compressed with gzip/bzip2/xz/lz4/lzip/lzo are uncompressed automatically. See Mail::SpamAssassin::ArchiveIterator for more details.

Please note that SpamAssassin is not designed to scan huge messages. Messages larger than ~10-20MB should not be fed to SpamAssassin, as memory consumption will increase rapidly.

OPTIONS

-e, --error-code, --exit-code

Exit with a non-zero error code, if the message is determined to be spam.

-h, --help

Print help message and exit.

-V, --version

Print version and exit.

-t, --test-mode

Test mode. Pipe message through and add extra report. Note that the report text assumes that the message is spam, since in normal use it is only visible in this case. Pay attention to the score instead.

If you run this with -d, the message will first have SpamAssassin markup removed before being tested.

-r, --report

Report this message as manually-verified spam. This will submit the mail message read from STDIN to various spam-blocker databases. Currently, these are the Distributed Checksum Clearinghouse https://www.dcc-servers.net/dcc/, Pyzor https://www.pyzor.org/, Vipul's Razor http://razor.sourceforge.net/, and SpamCop https://www.spamcop.net/.

If the message contains SpamAssassin markup, the markup will be stripped out automatically before submission. The support modules for DCC, Pyzor, and Razor must be installed for spam to be reported to each service. SpamCop reports will have greater effect if you register and set the spamcop_to_address option.

The message will also be submitted to SpamAssassin's learning systems; currently this is the internal Bayesian statistical-filtering system (the BAYES rules). (Note that if you only want to perform statistical learning, and do not want to report mail to third-parties, you should use the sa-learn command directly instead.)

-k, --revoke

Revoke this message. This will revoke the mail message read from STDIN from various spam-blocker databases. Currently, these are Vipul's Razor.

Revocation support for the Distributed Checksum Clearinghouse, Pyzor, and SpamCop is not currently available.

If the message contains SpamAssassin markup, the markup will be stripped out automatically before submission. The support modules for Razor must be installed for spam to be revoked from the service.

The message will also be submitted as 'ham' (non-spam) to SpamAssassin's learning systems; currently this is the internal Bayesian statistical-filtering system (the BAYES rules). (Note that if you only want to perform statistical learning, and do not want to report mail to third-parties, you should use the sa-learn command directly instead.)

--lint

Syntax check (lint) the rule set and configuration files, reporting typos and rules that do not compile correctly. Exits with 0 if there are no errors, or greater than 0 if any errors are found.

-W, --add-to-welcomelist

Previously --add-to-whitelist which will work interchangeably until 4.1.

Add all email addresses, in the headers and body of the mail message read from STDIN, to a persistent address welcomelist. Note that you must be running spamassassin or spamd with a persistent address list plugin enabled for this to work.

--add-to-blocklist

Previously --add-to-blacklist which will work interchangeably until 4.1.

Add all email addresses, in the headers and body of the mail message read from STDIN, to the persistent address blocklist. Note that you must be running spamassassin or spamd with a persistent address list plugin enabled for this to work.

-R, --remove-from-welcomelist

Previously --remove-from-whitelist which will work interchangeably until 4.1.

Remove all email addresses, in the headers and body of the mail message read from STDIN, from a persistent address list. STDIN must contain a full email message, so to remove a single address you should use --remove-addr-from-welcomelist instead.

Note that you must be running spamassassin or spamd with a persistent address list plugin enabled for this to work.

--add-addr-to-welcomelist

Previously --add-addr-to-whitelist which will work interchangeably until 4.1.

Add the named email address to a persistent address welcomelist. Note that you must be running spamassassin or spamd with a persistent address list plugin enabled for this to work.

--add-addr-to-blocklist

Previously --add-addr-to-blacklist which will work interchangeably until 4.1.

Add the named email address to a persistent address blocklist. Note that you must be running spamassassin or spamd with a persistent address list plugin enabled for this to work.

--remove-addr-from-welcomelist

Previously --remove-addr-from-whitelist which will work interchangeably until 4.1.

Remove the named email address from a persistent address welcomelist. Note that you must be running spamassassin or spamd with a persistent address list plugin enabled for this to work.

--ipv4only, --ipv4-only, --ipv4

Do not use IPv6 for DNS tests. Normally, SpamAssassin will try to detect if IPv6 is available, using only IPv4 if it is not. Use if the existing tests for IPv6 availability produce incorrect results or crashes.

-L, --local

Do only the ''local'' tests, ones that do not require an internet connection to operate. Normally, SpamAssassin will try to detect whether you are connected to the net before doing these tests anyway, but for faster checks you may wish to use this.

Note that SpamAssassin's network rules are run in parallel. This can cause overhead in terms of the number of file descriptors required if --local is not used; it is recommended that the minimum limit on fds be raised to at least 256 for safety.

-d, --remove-markup

Remove SpamAssassin markup (the "SpamAssassin results" report, X-Spam-Status headers, etc.) from the mail message. The resulting message, which will be more or less identical to the original, pre-SpamAssassin input, will be output to STDOUT.

(Note: the message will not be exactly identical; some headers will be reformatted due to some features of the Mail::Internet package, but the body text will be.)

-C path, --configpath=path, --config-file=path

Use the specified path for locating the distributed configuration files. Ignore the default directories (usually /usr/share/spamassassin or similar).

--siteconfigpath=path

Use the specified path for locating site-specific configuration files. Ignore the default directories (usually /etc/mail/spamassassin or similar).

--cf='config line'

Add additional lines of configuration directly from the command-line, parsed after the configuration files are read. Multiple --cf arguments can be used, and each will be considered a separate line of configuration. For example:

spamassassin -t --cf="body NEWRULE /text/" --cf="score NEWRULE 3.0"
--pre='config line'

Add additional lines of .pre configuration directly from the command-line, parsed before the configuration files are read. Multiple --pre arguments can be used, and each will be considered a separate line of configuration. For example:

spamassassin -t --pre="loadplugin Mail::SpamAssassin::Plugin::Foobar"
-p prefs, --prefspath=prefs, --prefs-file=prefs

Read user score preferences from prefs (usually $HOME/.spamassassin/user_prefs).

--progress

Prints a progress bar (to STDERR) showing the current progress. This option will only be useful if you are redirecting STDOUT (and not STDERR). In the case where no valid terminal is found this option will behave very much like the --showdots option in other SpamAssassin programs.

-D [area,...], --debug [area,...]

Produce debugging output. If no areas are listed, all debugging information is printed. Diagnostic output can also be enabled for each area individually; area is the area of the code to instrument. For example, to produce diagnostic output on bayes, learn, and dns, use:

spamassassin -D bayes,learn,dns

Use an empty string (-D '') to indicate no areas when the next item on the command line is a path, to prevent the path from being parsed as an area.

Higher priority informational messages that are suitable for logging in normal circumstances are available with an area of "info".

For more information about which areas (also known as channels) are available, please see the documentation at:

L<https://wiki.apache.org/spamassassin/DebugChannels>
-x, --nocreate-prefs

Disable creation of user preferences file.

--mbox

Specify that the input message(s) are in mbox format. mbox is a standard Unix message folder format.

--mbx

Specify that the input message(s) are in UW .mbx format. mbx is the mailbox format used within the University of Washington's IMAP implementation; see https://en.wikipedia.org/wiki/UW_IMAP.
