linux-qmail 病毒/垃圾邮件处理

vi /etc/sysconfig/spamassassin
SPAMDOPTIONS="-d -c -m5 -H -x -u vpopmail -v"
#spamassassin的过滤模板在/etc/mail/spamassassin/local.cf,修改为：
vi /etc/mail/spamassassin/local.cf
# These values can be overridden by editing ~/.spamassassin/user_prefs.cf
# (see spamassassin(1) for details)
# These should be safe assumptions and allow for simple visual sifting
# without risking lost emails.
required_score 7.0 以7.0为分界限,评分超过7.0的就会在邮件标题开头加入 ******SPAM*****字样,已提示为垃圾邮件,不过也有被误认为的时候.建议不要做对垃圾邮件删除.
