Announcements

It was found that what had been used until now as a basic lettre 0.10 MessageBuilder::body example failed to mention that for maximum compatibility with various email clients a Content-Type header should always be present in the message.

Before

Message::builder()
  // [...] some headers skipped for brevity
  .body(String::from("A plaintext or html body"))?

Patch

 Message::builder()
   // [...] some headers skipped for brevity
+  .header(ContentType::TEXT_PLAIN) // or `TEXT_HTML` if the body is html
   .body(String::from("A plaintext or html body"))?

Features

• Add support for rustls-native-certs when using rustls (#843)
