Email Self Hosters - what are you using?

电子邮件自托管用户——你们都在用什么？

At the moment I self host using maddy for a bunch of domains that need a mailbox or catch all. 目前，我正在使用 maddy 来为一堆需要邮箱或全收（catch-all）功能的域名进行自托管。

There are some minor issues with it - some are me, some are who knows. 它存在一些小问题——有些是我自己的原因，有些则原因不明。

The biggest bug bear is that the native email client on iOS takes an age to connect and download messages which causes some issues with OTP emails. 最让我头疼的是，iOS 原生邮件客户端连接并下载邮件的速度非常慢，这导致在接收 OTP（一次性密码）邮件时出现了一些问题。

So for those out there that do host their own email - what are you running, what would you change? 所以，对于那些同样自托管邮件服务的朋友们——你们正在运行什么方案？如果可以，你们会做出什么改变？
