924df208 | 108 | |
af435184 | 109 | SpamAssassin is one of the more popular spam filtering programs. |
a9cc50d9 BW |
110 | Get it from your local distribution or from the SpamAssassin web |
111 | site at URL `http://spamassassin.org/'. | |
924df208 | 112 | |
af435184 BW |
113 | To use SpamAssassin, add the following recipes to |
114 | \".procmailrc\": | |
924df208 | 115 | |
25173d93 | 116 | PATH=$PATH:/usr/bin/mh |

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