@lain @pwm @sun although I guess if Delta Chat devs release some new Chatmail feature that needs additional software I'll have to apply those changes to my server to use it. I don't really see anything groundbreaking happening there.

They did an incredible job on their Bots support too. There's an entire framework in Python and a newer one in Rust designed for creating bots. I haven't looked at the Rust one yet but the Python one comes with shell/cli commands already implemented which you can just augment as needed. I thought it would be a pain but you just give it a random email address and password, turn it on, and it works. Because first login attempt registers the account.

I wouldn't want to deal with writing a bot in Elixir as I don't have an appetite for dealing with IMAP/SMTP myself. But you could write it in anything if you really wanted to. No point when they've done so much work for you already though.
