将邮件从Protonmail导入Mailcow

Question

我正在尝试将电子邮件从Protonmail导入Mailcow。

当然，Mailcow具有同步作业功能，所以我显而易见的方法是创建一个这样的作业以从ProtonMail Bridge中提取电子邮件。该网桥在本地运行于127.0.0.1，其中端口1143用于IMAP，端口1025用于SMTP。我尝试通过键入以下内容与Ngrok一起公开它：

./ngrok http https://127.0.0.1:1143

然后，用Ngrok和1143提供的URL作为端口在Mailcow的UI（邮件设置->同步作业）中打开一个同步作业，这给了我：

Host2: sslcheck detected open ssl port 993 so turning ssl on (use --nossl2 --notls2 to turn off SSL and TLS wizardry)
SSL debug mode level is --debugssl 1 (can be set from 0 meaning no debug to 4 meaning max debug)
Host2: SSL default mode is like --sslargs2 "SSL_verify_mode=0", meaning for host2 SSL_VERIFY_NONE, ie, do not check the certificate server.
Host2: Use --sslargs2 SSL_verify_mode=1 to have SSL_VERIFY_PEER, ie, check the certificate server of host2

我为端口尝试了几种变体，同时还尝试了tls而不是http，但都没有成功：

./ngrok http https://127.0.0.1:1143
./ngrok tls -subdomain=encrypted 1143
./ngrok tls 1143

我也尝试通过tcp传输层访问ProtonMail Bridge：

./ngrok tcp 1143

tcp协议使我可以在同步作业中插入与ProtonMail Bridge的端口不同的端口（在下面的示例中为15926，与IMAP的1143相反：]]

我解决了无法将ProtonMail（通过Bridge）将电子邮件直接导入Mailcow（使用同步作业功能，该功能实现了imapsync）以及在计算机本地安装的isync/mbsync的失败。有几个步骤：
