|-原 2024年7月 Centos8系统上用宝塔安装宝塔邮局管理器 (亲测成功) 同理centos9 上应该也能搭建成功。
总结：还是要看日志，看到底是什么错误。

正式版9.1.0万能安装脚本不支持Centos8这样的系统
安装时会提示失败：
Centos7/8官方已经停止支持
如是新安装系统服务器建议更换至Debian-12/Ubuntu-22/Centos-9系统安装宝塔面板
服务器是国外的主机商的服务器，国内像腾讯云和阿里云默认都不开放25端口，要申请开放25端口，但是申请通过并不容易。建议直接用国外的主机。
另外有些主机商的服务器在控制台上是有设置防火墙的，要放行下25等端口(20240730)。
安装用的操作系统Centos 8
硬件单核CPU，内存768MB
第一步是确保系统软件包是最新的(很重要)。为此，请按如下所示更新系统：
# dnf update
继续之前，还请确保不存在其他 MTA（如 Sendmail），因为这将导致与 Postfix 配置冲突。例如，要删除 Sendmail，请运行以下命令：
# dnf remove sendmail
可以先查看下主机名
hostname
并查看下hosts
cat /etc/hosts
如果都ok的话，跳过第二步
步骤 2）设置主机名并更新 /etc/hosts
使用下面的 hostnamectl 命令在系统上设置主机名：
# hostnamectl set-hostname server1.crazytechgeek.info # exec bash
此外，你需要在 /etc/hosts 中添加系统的主机名和 IP：
# vi /etc/hosts 192.168.1.13 server1.crazytechgeek.info
保存并退出文件。
步骤3)
宝塔面板安装Redis
安装redis之前会先安装必要的环境库，之后再安装redis
总共耗时不到10分钟，安装redis花费的时间有点久
第四步
安装宝塔邮局管理器
在这里卡了会

总结：还是要看日志，看到底是什么错误。
warning: sqlite:/etc/postfix/sqlite_virtual_alias_maps.cf is unavailable. unsupported dictionary type: sqlite
服务器是国外的主机商的服务器，国内像腾讯云和阿里云默认都不开放25端口，要申请开放25端口，但是申请通过并不容易。建议直接用国外的主机。
安装用的操作系统Centos stream 9
硬件单核CPU，内存1.25GB
第一步是确保系统软件包是最新的(很重要)。为此，请按如下所示更新系统：
# dnf update
再
sudo update-crypto-policies --set LEGACY
再
curl https://rspamd.com/rpm-stable/centos-9/rspamd.repo > /etc/yum.repos.d/rspamd.repo # For Centos-9 rpm --import https://rspamd.com/rpm-stable/gpg.key yum update
再
dnf --enablerepo=epel install opendkim opendkim-tools
再
安裝redis和宝塔邮局管理器
有一次在Centos 9上安装时，遇到未就绪的比较多
- 如果邮局环境异常，请先排除故障。 请在所有异常修复完成后执行下一步操作
之后安装参考下面的

第一次测试发送邮件
发送邮件失败,错误原因[[Errno 111] Connection refused]
发现master.cf内容为空
于是从centos8上安装好的postfix拿了一份配置文件
