The stub transport only logs message envelope and drops the content. It can be useful for testing purposes.

{{< highlight rust >}} use lettre::stub::StubEmailTransport; use lettre::{SimpleSendableEmail, EmailTransport};

let email = SimpleSendableEmail::new( "user@localhost", vec!["root@localhost"], "message_id", "Hello world" );

let mut sender = StubEmailTransport; let result = sender.send(email); assert!(result.is_ok()); {{< /highlight >}}

Will log the line:

b7c211bc-9811-45ce-8cd9-68eab575d695: from=<user@localhost> to=<root@localhost>
