If you just need email forwarding... without logs and no storage to disk... here's something I made: https://forwardemail.net
Also, improvmx.com is a great product as well.
If you like open source, https://maddy.email/ is a single binary deployment that can handle everything even IMAP.
https://mailcow.github.io/mailcow-dockerized-docs/ is a dockerize solution with super detail document as well.
Suggest you hire an editor to fix up your content… or contact me and I’ll do it for free.
