使用SpamAssassin来过滤垃圾邮件

安装了SpamAssassin，因为听说是目前最NB的SPAM过滤软件了。于是又开始到处查阅如何进行配置。
发现，SpamAssassin基本不用改动。只需要改动.procmail。改动如下：

MAILDIR=$HOME/Mail
DEFAULT=$MAILDIR/inbox/
LOGFILE=$HOME/Logs/procmail.log
VERBOSE=off
NL=""

:0fw
# The following line tells Procmail to send messages to SpamAssassin only if they are less than 256000 bytes. Most spam falls well below this size and a larger size could seriously affect performance.
* <256000
| /usr/bin/spamassassin -P

:0e
{
EXITCODE=$?
}

:0
* ^X-Spam-Status: Yes
$MAILDIR/spam/

:0
* .*
$MAILDIR/inbox/

保存！运行mutt，发现一切OK！
