A SMTP server that can be embedded into another program

This library provides a simple embeddable SMTP server. The server uses blocking IO and a threadpool.

Examples

use mailin_embedded::{Server, SslConfig, Handler};

#[derive(Clone)]
struct MyHandler {}
impl Handler for MyHandler{}

let handler = MyHandler {};
let mut server = Server::new(handler);

server.with_name("example.com")
   .with_ssl(SslConfig::None)?
   .with_addr("127.0.0.1:25")?;
server.serve_forever();

SSL

The mailin-embedded library requires an SSL implementation. The SSL implementation is selected with a feature:

Using RustTLS (the default and recommended, so far no compatibility problems):

$ cargo build

Using OpenSSL (with Mozilla modern):

$ cargo build --features "ossl"

The SSL configuration for both of these libraries is quite strict and might not work with some older Email servers. However, until now, I have only seen problems with spammers and no problems with real email servers.

Using in Cargo.toml

mailin-embedded = "^0"
