I just put some of the code on my Github. It's pretty raw, but should be
enough to get started with. I have the code for the send and receive
sides of the Telegram bot and the Youtube-dl downloader.

Youtube-dl Bot: https://github.com/Koshroy/yt-nncp
Telegram Receipt Relay Bot: https://github.com/Koshroy/telegram-nncp-bot
Telegram Send Relay Bot: https://github.com/Koshroy/telegram-send-bot

Feel free to let me know if you have any questions!

I have plans to convert the Telegram bot into a bot that uses an MDA to
actually relay received Telegram messages as mail, and then have a fake
MTA which parses incoming mail as messages to send out to Telegram. I'm
also planning on porting all of this to use the Matrix network as well,
but I have more friends/family on Telegram right now so that's what I'm
more interested in connecting first. I'm not super familiar with how
E-Mail works underneath so it's a bit of a learning experience for me.

Oh isn't this a bit dangerous? I've never used a flow like this so I'm
not sure, but isn't it a bit scary to apply package/system updates
completely unattended like this?

Oh, I might be interested in an NNCP Usenet feed!

Also, is there any group of folks exchanging mail over NNCP? I realize
that with this mailing list there might not be much of a need, but it
would be cool to exchange mail over NNCP! I've been wiring up a local
Postfix MTA to NNCP for use between machines of mine.

Thanks,
Koushik
