CentOS 6 已經EOL，所以要增加yum repository
1. cd /etc/yum.repos.d/
2. sed -i 's|#baseurl=http://mirror.centos.org/centos/$releasever|baseurl=http://vault.centos.org/6.10|g' CentOS-Base.repo

設定spamassassin
6.vim /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.
