I always want to have a programmable mailserver, but not just for filtering. I hope it can also do things like calling API then react according to the respond etc. It's like a eBPF program but for mailservers. I'm not sure Sieve is a language that enables such usage. I know maybe it's a domain-specific language, but since it's a language capable of programming the server, I would rather expect more from it than "it's just yet another way to configure your mail filter".

Sieve seems not powerful enough. I had this though experiment a few days ago: What if you could run code in a sandbox on the server (javascript, webassembly?) with api's (provided by the server) to access mailboxes/messages and to take actions (move to folder, change message flags), and perhaps some networking (e.g. dns blocklist)?
