B4J Question How can create own mail server with Jetty?

[tummosoft]

Hi everybody!
I have a Linux VPS running Ubuntu 18. I want to build a mail server (SMTP, POP3) on this machine without third party smtp server (exam smtp.gmail.com).
I create an MX record ( mailer.mydomain.com) and open port 25. I write some code with socket try to listen on port 25, and send a email. But my code don't receive any data.
I have a question: How can create own mail server with B4J?
Thank a lot!

Jetty is a http / websocket server. You need to use ServerSocket and implement the relevant protocols. Not trivial.

FTP server example: [B4X] FTP Server implemented with Socket and AsyncStreams
