I’m toying with the idea of doing a fairly specialized incoming SMTP proxy and I’m considering Elixir for the task due to performance, concurrency, and pattern matching.
However, I can’t find any reliable libraries or examples. At a very high level this Proxy would switch between the Internet and the actual email server and filter/parse/handle incoming emails to a particular domain. e.g. MX public records for example.com are pointing to this server which will handle incoming emails filter out and pass them through to google apps email servers for the user to digest.
