既然产品名称叫BillionMail并且使用PostgreSQL作为后端数据库，那为什么不能业务应用层和数据存储层分布式运行，非得要用docker镜像安装绑死本机数据库？

PostgreSQL本身相比MySQL就更适合大规模分布式，却在你们这个产品里面不能分布式那怎么做到BillionMail呢？单机硬件配置需要多大的规模才能撑得起BillionMail？ 难道你们的志向只想要自己有Billion个终端应用，却不希望更近一步你们的用户能拥有Billion个mail吗，所以在这个最基本的可选数据库连接功能上限制用户？ 建议在初始化安装的时候增加一个可选项，可选使用现有的外部数据库或安装本机数据库， 另外期待增加可选MySQL数据库，全世界用MySQL的人更多，用户上手使用你们产品的成本就更低，更利于BillionMail产品推广 最后问一下这个项目有捐赠渠道吗，我发工资了可以捐500聊表心意
