我在任何电子邮件中都没有收到bayes分数，尽管我尽了最大的努力，但似乎没有贝氏过滤。我不是Linux和spamassassin专家，所以我要求一些帮助。Spamassassin Bayes无法正常工作
我已经建立了在local.cf这些设置在试图获得贝叶斯工作：
use_bayes 1
bayes_auto_learn 1
bayes_min_ham_num 100
bayes_auto_learn_threshold_nonspam -0.001
bayes_auto_learn_threshold_spam 6.0
allow_user_rules 0
add_header all Status _YESNO_, score=_SCORE_ required=_REQD_ tests=_TESTS_ autolearn=_AUTOLEARN_ version=_VERSION_
SpamAssassin的日志文件显示一个错误始终如一：
Fri Mar 3 12:36:27 2017 [10104] info: spamd: creating default_prefs: /root/.spamassassin/user_prefs
Fri Mar 3 12:36:27 2017 [10104] info: spamd: failed to create readable default_prefs: /root/.spamassassin/user_prefs
和一个偶尔的错误：
warn: plugin: eval failed: bayes: (in learn) locker: safe_lock: cannot create tmp lockfile /root/.spamassassin/bayes.lock.[mydomain.com].27903 for /root/.spamassassin/bayes.lock: Permission denied
/root/.spamassassin/user_prefs确实存在，我给每个人都允许离子它试图解决这个问题，有没有效果：
-rwxrwxrwx 1 root root 1273 Mar 1 14:46 user_prefs*
我spamd的启动命令明确地设置用户为spamd的，但最主要的还是服务作为根运行时，孩子似乎是正确产卵。以下是ps的输出：
root 10093 0.0 1.5 145988 66952 ? Ss 02:25 0:05 /usr/sbin/spamd --create-prefs --max-children=5 --username=spamd --helper-home-dir=/var/log/spamassassin/ --syslog=/var/log/spamassassin/spam .log -d --pidfile=/var/run/spamd.pid

spamd 23753 0.0 1.7 151732 72000 ? S 10:30 0:02 spamd child
我的贝叶斯数据库存在于根：
sa-learn --dump magic
0.000 0 3 0 non-token data: bayes db version
0.000 0 1727 0 non-token data: nspam

我所有的电子邮件标题要么这些，尽管我强迫与上面显示的阈值，自学习功能：
autolearn=unavailable autolearn_force=no
或
autolearn=no autolearn_force=no
最后，这里是展示它识别垃圾邮件，但不应用任何贝叶斯处理SpamAssassin的日志的完整片段，而工作显然为根：

问题是bayes数据库在/root/.spamassassin中，并且子进程无法访问它？它应该在哪里，还是其他的东西？在我有限的知识结束这一点。任何帮助赞赏。
我的回答如下解决。 –
