and body structure. Addresses in To, From fields etc are parsed into
Address types.
```rust use melib::{Attachment, Envelope};
let rawmail = r#"From: "some name" some@example.com To: "me" myself@example.com Cc: Subject: =?utf-8?Q?gratuitouslyencodedsubject?= Message-ID: h2g7f.z0gy2pgaen5m@example.com MIME-Version: 1.0 Content-Type: multipart/mixed; charset="utf-8"; boundary="bzzbzzbzz"
This is a MIME formatted message with attachments. Use a MIME-compliant client to view it properly. --bzz_bzzbzz
hello world. --bzzbzzbzz Content-Type: image/gif; name="testimage.gif"; charset="utf-8" Content-Disposition: attachment Content-Transfer-Encoding: base64
