Raw

v0.10.0 (unreleased)

Upgrade notes

Several breaking changes were made between 0.9 and 0.10, but changes should be straightforward:

  • MSRV is now 1.49
  • The lettre_email crate has been merged into lettre. To migrate, replace lettre_email with lettre::message and make sure to enable the builder feature (it's enabled by default).
  • SendableEmail has been renamed to Email and EmailBuilder::build() produces it directly. To migrate, rename SendableEmail to Email.
  • The serde-impls feature has been renamed to serde. To migrate, rename the feature.

Features

  • Add tokio 1 support
  • Add rustls support
  • Add async-std support. NOTE: native-tls isn't supported when using async-std for the smtp transport.
  • Allow enabling multiple SMTP authentication mechanisms
  • Allow providing a custom message id
  • Allow sending raw emails

Breaking Changes

  • Merge lettre_email into lettre
  • Merge Email and SendableEmail into lettre::message::Email
  • SmtpTransport is now an high level SMTP client. It provides connection pooling and shortcuts for building clients using commonly desired values
  • Refactor TlsParameters implementation to not expose the internal TLS library
  • FileTransport writes emails into .eml instead of .json
  • When the hostname feature is disabled or hostname cannot be fetched, 127.0.0.1 is used instead of localhost as EHLO parameter (for better RFC compliance and mail server compatibility)
  • The new method of ClientId is deprecated
  • Rename serde-impls feature to serde
  • The SendmailTransport now uses the sendmail command in current PATH by default instead of /usr/bin/sendmail.

Bug Fixes

  • Fix argument injection in SendmailTransport (see RUSTSEC-2020-0069)
  • Correctly encode header values containing non-ASCII characters
  • Timeout bug causing infinite hang
  • Fix doc tests in website
  • Fix docs for domain field

Misc

  • Improve documentation, examples and tests
  • Replace line-wrap, email, bufstream with our own implementations
  • Remove bytes
  • Remove time
  • Remove fast_chemail
  • Update base64 to 0.13
  • Update hostname to 0.3
