请问，为什么我的mail server把所有的邮件都当成垃圾邮件给过滤掉了
$sa_tag_level_deflt  = 8.0;  
$sa_tag2_level_deflt = 10;
$sa_kill_level_deflt = 10;
$sa_dsn_cutoff_level = 9;  
－－－－－－－－－－－－－－
$final_virus_destiny      = D_REJECT;
$final_banned_destiny     = D_BOUNCE;
$final_spam_destiny       = D_REJECT;
$final_bad_header_destiny = D_PASS;
如果把$final_spam_destiny更改为D_PASS就可以发送，不过发送的所有邮件都打上SPAM标识

以下是在网上的类似问题，但都没有结果：

经过对SPAM判定分数的更改，发现我把分数改成10以后，就可以正常发送邮件而不会被当作垃圾邮件过滤，但还只是一部分，看来得多实验才能知道我自己的mail server适合的分数是多少了。现在疑问就是如何确定适合我的server的判定分数呢

根据自己的情况了，我的一般设置在10

少加点规则，这样就会好很多。

谢谢，暂时先自己多尝试摸索先
