indymilter

(in development)

Stand-alone asynchronous milter library.

pure safe Rust, no dependency on C library
asynchronous paradigm, implementation based on Tokio
free software

Example

Here is a simple but complete milter program that logs client IP addresses:

```rust use indymilter::{Callbacks, Context, SocketInfo, Status}; use tokio::{net::UnixListener, signal};

[tokio::main]

async fn main() { let config = Default::default();

let callbacks = Callbacks::new()
    .on_connect(|context, _, socket_info| {
        Box::pin(handle_connect(context, socket_info))
    });

let listener = UnixListener::bind("/run/ipmilter.sock")
    .expect("cannot open milter socket");

indymilter::run(listener, callbacks, config, signal::ctrl_c())
    .await
    .expect("milter execution failed");

}

async fn handleconnect( _: &mut Context<()>, socketinfo: Option, ) -> Status { if let Some(SocketInfo::Inet(addr)) = socket_info { println!("connect from {}", addr.ip()); }

Status::Continue

} ```
