SpamAssassin is a mail filter to identify spam.
|
|
|
|
Using its rule base, it uses a wide range of heuristic tests on mail
|
|
headers and body text to identify "spam", also known as unsolicited
|
|
commercial email.
|
|
Once identified, the mail can then be optionally tagged as spam for
|
|
later filtering using the user's own mail user-agent application.
|
|
|
|
The spam-identification tactics used include header analysis, text
|
|
analysis, a Bayesian-style form of probability-analysis classification,
|
|
blacklists and Razor.
|
|
|
|
The distribution provides a command line tool to perform filtering,
|
|
along with Mail::SpamAssassin, a set of perl modules which implement a
|
|
Mail::Audit plugin, allowing SpamAssassin to be used in a Mail::Audit
|
|
filter.
|
|
In addition, there is "spamd", a persistently running, daemonized
|
|
version of the command line tool "spamassassin". Together with the small
|
|
client "spamc" this allows processing of large volumes of mail without
|
|
the cost of starting the perl interpreter for each one.
|
|
|
|
SpamAssassin does not deliver mail to the users mailbox. You need a
|
|
different program (procmail is recommended) for local mail delivery.
