# use-smtp

SMTP protocol vocabulary primitives for `RustUse`.

## Experimental

`use-smtp` is experimental while `use-email` remains below `0.3.0`.

## Example

```rust
use use_smtp::{MailFrom, RcptTo, SmtpCommand, SmtpReply, SmtpReplyCode};

let mail_from = SmtpCommand::MailFrom(MailFrom::new("bounce@example.com")?);
let rcpt_to = SmtpCommand::RcptTo(RcptTo::new("jane@example.com")?);
let reply = SmtpReply::new(SmtpReplyCode::new(250)?, "OK")?;

assert_eq!(mail_from.to_string(), "MAIL FROM:<bounce@example.com>");
assert_eq!(rcpt_to.to_string(), "RCPT TO:<jane@example.com>");
assert_eq!(reply.to_string(), "250 OK");
# Ok::<(), Box<dyn std::error::Error>>(())
```

## Scope

- SMTP command, reply, reply code, enhanced status code, extension, EHLO keyword, MAIL FROM, RCPT TO, DATA, QUIT, and capability markers.
- Protocol vocabulary only.

## Non-goals

- Network client behavior.
- TLS negotiation.
- Authentication, delivery, retry, queue, or provider integration.
