Spamassassin中文规则问题

owenbush

最近搭建CentOS6.4 + postfix + dovecot + cyrus sasl + courier-authlib  + maildrop + extmail + mysql + apache + amavisd-new + clamav + spamassassin.

好不容易做到Spamassassin环节的时候,突然发现中文规则, chinese_rule.cf, 已经好久不更新了(失落的极点);请问各位大侠
1.有没有最新的垃圾邮件中文过滤规则和已下载到
2.Spamassassin英文规则是否是一直在更新呢?
3.如果没有,有没有类似spamassassin,开源的, 可用的,随时可更新的反垃圾软甲可用呢,请各位不吝推荐几款,先谢过了.

4.vim 打开chinese_rule.cf中文是乱码,正常吗?
header CN_SUBJECT_1     Subject =~ /ÓÅ»Ý/
describe CN_SUBJECT_1   Subject contains "ÓÅ»Ý"
score CN_SUBJECT_1      1.254

header CN_SUBJECT_5     Subject =~ /ºÏ×÷/
describe CN_SUBJECT_5   Subject contains "ºÏ×÷"
score CN_SUBJECT_5      0.233

header CN_SUBJECT_6     Subject =~ /·¢Æ±/
describe CN_SUBJECT_6   Subject contains "·¢Æ±"
score CN_SUBJECT_6      0.055

header CN_SUBJECT_9     Subject =~ /ʵҵ/
describe CN_SUBJECT_9   Subject contains "ʵҵ"
score CN_SUBJECT_9      1.226

header CN_SUBJECT_12    Subject =~ /´ú¿ª/
describe CN_SUBJECT_12  Subject contains "´ú¿ª"
score CN_SUBJECT_12     2.460

header CN_SUBJECT_13    Subject =~ /Ʊ£¡/
describe CN_SUBJECT_13  Subject contains "Ʊ£¡"
score CN_SUBJECT_13     0.039

header CN_SUBJECT_25    Subject =~ /¸÷Àà/
