System Procmail Rules<\/span><\/p>\n

\u00a0\u00a0\u00a0\u00a0 Procmail is used as the local mail delivery agent and also to invoke <\/span>SpamAssassin to tag suspected spam<\/span>. Because it is the default local delivery agent, a .forward is not required to invoke procmail rules<\/strong>. For those of you who are already <\/span>familiar with procmail, here are the system-wide rules:<\/span><\/span><\/p>\n

     DROPPRIVS=yes\r\n     MAILDIR=$HOME\/mail\r\n     INCLUDERC=\/etc\/mail\/spamassassin\/spamassassin-default.rc\r\n     :0:\r\n     * ? test ! -f $HOME\/.procmailrc\r\n     * ^X-Spam-Status: Yes\r\n     spam\r\n<\/span><\/pre>\n
\u00a0\u00a0\u00a0\u00a0 The first rule causes procmail to execute with the recipients <\/span>permissions for security reasons and also to ensure that spamassassin <\/span>reads your user preferences and creates files with your ownership so you <\/span>can edit them.<\/span><\/span><\/p>\n
\u00a0\u00a0\u00a0\u00a0 The next rule tells procmail that your mail folders are located in a <\/span>subdirectory called “mail” in your home directory. Then <\/span>procmail calls spam assassin to evaluate mail as spam or non-spam and add <\/span>an X-Spam-Status: line with a Yes\/No result.<\/span><\/span><\/p>\n
\u00a0\u00a0\u00a0\u00a0 Next, we check to see if you have your own “.procmailrc” <\/span>file. If you do not, we place any mail tagged as spam in your <\/span>“spam” mail folder. If you do have your own <\/span>“.procmailrc” file, then we only tag the spam and leave it up to <\/span>your rules to determine what to do with it.<\/span><\/span><\/p>\n
Simple Examples<\/span><\/strong><\/p>\n
\u00a0\u00a0\u00a0\u00a0 If you want to send all e-mail that is scored as spam by spamassassin <\/span>to your spam folder, the following rule would do it. This is also the <\/span>default behavior if you have no .procmailrc at all.<\/span><\/span><\/p>\n
     :0:\r\n     * ^X-Spam-Status: Yes\r\n     spam\r\n<\/span><\/pre>\n
\u00a0\u00a0\u00a0\u00a0 If you are extremely trusting<\/strong> and just want to discard all e-mail that <\/span>spamassassin determines to be spam, the following rule would do that.<\/span><\/span><\/p>\n
     :0:\r\n     * ^X-Spam-Status: Yes\r\n     \/dev\/null\r\n<\/span><\/pre>\n
\u00a0\u00a0\u00a0\u00a0 On Linux and other Unix-like operating systems, \/dev\/null is a data <\/span>sink. That is any data sent to it is discarded.<\/span><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
