"mass-check" is a tool included with the SpamAssassin source distribution in the 'masses' directory, which can be found in the SVN repository, to test rules for accuracy and hit-rate. If you're writing custom rules, you really should use this to test them.
First, you need HandClassifiedCorpora. Let's say that's divided into two maildir made up of two mbox folders, "/path/to/ham" and "/path/to/spam".

cd masses
./mass-check --progress \
ham:dirmbox:/path/to/ham \
spam:dirmbox:/path/to/spam
|
This will create two files, "ham.log" and "spam.log" containing hit-rates from the hitting rules in , read from the rules dir "../rules" as they are applied to that corpus. Each line of the two log files represents details about one email message, and there's a line for every message.
mass-check also takes other options to control whether network tests are run, whether multiple processes are run in parallel, how the output is presented, etc.; read the comments at the top of the file for details. Here's some key bits:
Configuration File
Mass-check reads a "user_prefs" file in "spamassassin/user_prefs". You need to create this yourself, it will not be created for you.
To test your own rules, you'll need to put them in this file, and include a line containing "allow_user_rules 1"
Using network tests
for For mass-checks for scoresets 1 or 3, using network tests, you need to provide the --net switch. Ensure Net::DNS, Mail::SPF, Mail::QueryDKIM (at least 0.31, preferably 0.36_5 or later), Razor , pyzor (InstallingRazor), Pyzor (InstallingPyzor) and DCC (InstallingDCC) are installed.
Network tests are slow unless you use the -j switch to allow mass-check to start multiple parallel scanning processes.

Once mass-check completes
The If you're using mass-check to test your own rules, the next step is to run hit-frequencies: see HitFrequencies for details. Alternatively, if you're submitting data for a new scoreset, see RescoreMassCheck, or NightlyMassCheck for the nightly QA test.
Usage
| Wiki Markup |
|---|
mass-check \[options\] target ... |
-c=file | set configuration/rules directory |
-p=dir | set user-prefs directory |
-f=file | read list of targets from <file> |
-j=jobs | specify the number of processes to run simultaneously |
--net | turn on network checks! |
--mid | report Message-ID from each message |
--debug | report debugging information |
--progress | show progress updates during check |
--rewrite=OUT | save rewritten message to OUT (default is /tmp/out) |
--showdots | print a dot for each scanned message |
--rules=RE | Only test rules matching the given regexp RE |
--restart=N | restart all of the children after processing N messages |
--deencap=RE | Extract SpamAssassin-encapsulated spam mails only if they were encapsulated by servers matching the regexp RE (default = extract all SpamAssassin-encapsulated mails) |
log options
-o | write all logs to stdout |
--loghits | log the text hit for patterns (useful for debugging) |
--loguris | log the URIs found |
--hamlog=log | use <log> as ham log ('ham.log' is default) |
--spamlog=log | use <log> as spam log ('spam.log' is default) |
message selection options
-n | no date sorting or spam/ham interleaving |
--after=N | only test mails received after time_t N (negative values are an offset from current time, e.g. -86400 = last day) or after date as parsed by Time::ParseDate (e.g. '-6 months') |
--before=N | same as --after, except received times are before time_t N |
--cache | Use cached information about atime (generates files in corpus area) |
--all | don't skip big messages |
--head=N | only check first N ham and N spam (N messages if -n used) |
--tail=N | only check last N ham and N spam (N messages if -n used) |
simple target options (implies -o and no ham/spam classification)
--dir | subsequent targets are directories |
--file | subsequent targets are files in RFC 822 format |
--mbox | subsequent targets are mbox files |
--mbx | subsequent targets are mbx files |
Just left over functions we should remove at some point:
--bayes | report score from Bayesian classifier |
Usage: Targets
non-option arguments are used as target names (mail files and folders), the target format is: <class>:<format>:<location>
class | is "spam" or "ham" |
format | is "detect", "dir", "file", "mbx", or "mbox" |
location | is a file or directory name. Globbing of ~ and * is supported. |
"detect" is the easiest format to use. This assumes "mbox" for any file whose path contains the pattern "/\.mbox/i", "directory" for anything that is a directory, or "file" otherwise.CategorySoftware
