?宝塔安装邮局，提示Rspamd未安装,请点击修复按钮 ，点修复几次没有效果，只能手动安装Rspamd了
手动安装：
[root@l]# yum install -y rspamd

Error:
Problem: conflicting requests
- nothing provides libunwind.so.8()(64bit) needed by rspamd-3.2-1.x86_64
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)?意思是需要安装一个依赖项，搜索了很多资料，终于搞定了，包地址：libunwind-1.5.0-alt1.x86_64.rpm ALT Linux P10 Download
rpm -Uvh https://download-ib01.fedoraproject.org/pub/epel/8/Everything/x86_64/Packages/l/libunwind-1.3.1-3.el8.x86_64.rpm然而再安装出现了证书错误：
[root@i7do ~]# rpm -Uvh https://download-ib01.fedoraproject.org/pub/epel/8/Everything/x86_64/Packages/l/libunwind-1.3.1-3.el8.x86_64.rpm
Retrieving https://download-ib01.fedoraproject.org/pub/epel/8/Everything/x86_64/Packages/l/libunwind-1.3.1-3.el8.x86_64.rpm
curl: (77) error setting certificate verify locations:

error: skipping https://download-ib01.fedoraproject.org/pub/epel/8/Everything/x86_64/Packages/l/libunwind-1.3.1-3.el8.x86_64.rpm - transfer failed
于是，修复证书：
wget http://curl.haxx.se/ca/cacert.pem
cat cacert.pem > /etc/pki/tls/certs/ca-bundle.crt
点提交后，还是提示修复，于是设置了 redis 密码，现在好了
