Quick Spam Filter (qsf) is a small, fast spam filter that works by learning
to recognise the words that are more likely to appear in spam than non-spam.
It is intended to be used in a procmail recipe to mark email as being
Fast, intelligent, automatic spam detector using Bayesian analysis of word
counts in spam and non-spam email. Intended for use with procmail to
filter inbound email. No manual rule creation required.
The dovecot antispam plugin watches a defined spam folder (defaults to
"SPAM"). Instead of moving mail into special folders or forwarding
them to special mail addresses for retraining, the plugin offers two
actions for the user:
1. moving mail out of the SPAM folder and
2. moving mail into the SPAM folder.
The dovecot plugin watches these actions (and additionally prohibits
APPENDs to the SPAM folder, more for technical reasons than others)
and tells the spam classifier that it made an error and needs to
re-clas- sify the message (as spam/not spam depending on which way it
DSPAM (as in De-Spam) is an open-source project to create a new kind
of anti-spam mechanism, and is currently effective as both a
server-side agent for UNIX email servers and a developer's library
for mail clients, other anti-spam tools, and similar projects
requiring drop-in spam filtering.
This module is designed so that users of the Sendmail::Milter module (or other
Sendmail programmers) can ascertain if a user has elected to whitelist
themselves as a "spam friend" (where there should be no spam filtering on mail
to them) or, where spam-filtering is not the default, but an option, where
certain receipients have been labeled as "spam haters".
The Spam Bouncer is a set of procmail recipes, or instructions, which
search the headers and text of your incoming email to see if it meets
one or more of several categories (known addresses, rogue ISPs, bulk
mail software etc etc).
The Spam Bouncer sorts suspected spam into two categories -- mail from
known spam sources which is definitely spam, and other mail which is
probably spam, but might also be legitimate. It then tags this email
with appropriate headers giving the spam classification, and responds
according to the parameters you have set.
This plugin adds "mark as spam" or "mark as not spam" button to the message
menu. When not in the Junk mailbox, messages are moved into the Junk mailbox
and marked as read. When in the Junk mailbox, the buttons are changed to "mark
as not spam" or "this message is not spam" and the message is moved to the
Inbox. The learning driver allows you to perform additional processing on each
message marked as spam/ham.
