924df208 | 109 | |
af435184 | 110 | SpamAssassin is one of the more popular spam filtering programs. |
a9cc50d9 BW |
111 | Get it from your local distribution or from the SpamAssassin web |
112 | site at URL `http://spamassassin.org/'. | |
924df208 | 113 | |
af435184 BW |
114 | To use SpamAssassin, add the following recipes to |
115 | \".procmailrc\": | |
924df208 | 116 | |
25173d93 | 117 | PATH=$PATH:/usr/bin/mh |

130 | * ^X-Spam-Status: Yes | |
131 | spam/. | |
924df208 | 132 | |
5a4aad03 | 133 | If you don't use \"spamc\", use \"spamassassin -P -a\". |
924df208 | 134 | |
af435184 BW |
135 | Note that one of the recipes above throws away messages with a |
136 | score greater than or equal to 10. Here's how you can determine a | |
137 | value that works best for you. | |
924df208 | 138 | |
af435184 BW |
139 | First, run \"spamassassin -t\" on every mail message in your |
140 | archive and use Gnumeric to verify that the average plus the | |
141 | standard deviation of good mail is under 5, the SpamAssassin | |
142 | default for \"spam\". | |
924df208 | 143 | |
af435184 BW |
144 | Using Gnumeric, sort the messages by score and view the messages |
145 | with the highest score. Determine the score which encompasses all | |
146 | of your interesting messages and add a couple of points to be | |
147 | conservative. Add that many dots to the \"X-Spam-Level:\" header | |
148 | field above to send messages with that score down the drain. | |
924df208 | 149 | |
af435184 BW |
150 | In the example above, messages with a score of 5-9 are set aside |
151 | in the \"+spam\" folder for later review. The major weakness of | |
152 | rules-based filters is a plethora of false positives so it is | |
153 | worthwhile to check. | |
924df208 | 154 | |
af435184 BW |
155 | If SpamAssassin classifies a message incorrectly, or is unsure, |
156 | you can use the MH-E commands \\[mh-junk-blacklist] and | |
2dcf34f9 | 157 | \\[mh-junk-whitelist]. |
924df208 | 158 | |
af435184 BW |
159 | The command \\[mh-junk-blacklist] adds a \"blacklist_from\" entry |
160 | to \"~/spamassassin/user_prefs\", deletes the message, and sends | |
161 | the message to the Razor, so that others might not see this spam. | |
162 | If the \"sa-learn\" command is available, the message is also | |
163 | recategorized as spam. | |
924df208 | 164 | |
af435184 BW |
165 | The command \\[mh-junk-whitelist] adds a \"whitelist_from\" rule |
166 | to the \"~/.spamassassin/user_prefs\" file. If the \"sa-learn\" | |
167 | command is available, the message is also recategorized as ham. | |
2dcf34f9 BW |
168 | |
169 | Over time, you'll observe that the same host or domain occurs | |
af435184 BW |
170 | repeatedly in the \"blacklist_from\" entries, so you might think |
171 | that you could avoid future spam by blacklisting all mail from a | |
172 | particular domain. The utility function | |
173 | `mh-spamassassin-identify-spammers' helps you do precisely that. | |
174 | This function displays a frequency count of the hosts and domains | |
175 | in the \"blacklist_from\" entries from the last blank line in | |
176 | \"~/.spamassassin/user_prefs\" to the end of the file. This | |
2dcf34f9 | 177 | information can be used so that you can replace multiple |
5a4aad03 | 178 | \"blacklist_from\" entries with a single wildcard entry such as: |
924df208 | 179 | |
f0d73c14 | 180 | blacklist_from *@*amazingoffersdirect2u.com |
924df208 | 181 | |
2dcf34f9 | 182 | In versions of SpamAssassin (2.50 and on) that support a Bayesian |
af435184 BW |
183 | classifier, \\[mh-junk-blacklist] uses the program \"sa-learn\" |
184 | to recategorize the message as spam. Neither MH-E, nor | |
185 | SpamAssassin, rebuilds the database after adding words, so you | |
186 | will need to run \"sa-learn --rebuild\" periodically. This can be | |
187 | done by adding the following to your crontab: | |
924df208 | 188 | |
dda00b2c | 189 | 0 * * * * sa-learn --rebuild > /dev/null 2>&1" |
