"Internet Message Format" meticulously implemented for email construction and validation, as defined in RFC 5322 and other RFCs.
- Parses bytes into an Email structure (represented internally as a tree) and validates
RFC 5322 "Internet Message Format" compliance.
- Extensive RFC 5322 Parser/validator: If you generate an email using this crate, you are guaranteed that will be a valid RFC 5322 formatted email, or else you will get a ParseError. The only exception that I am currently aware of is that lines can be longer than 998 characters (see issue #3).
- Streams an Email structure back into bytes.
- Generates and modifies Email structures using functions like
- Integrates with lettre
(enable optional feature
lettre) and mailstrom
- Supports chrono
Tmfor setting the
Datefield (enable optional feature
- Valid emails are 7-bit ASCII, and this crate requires all content to be 7-bit ASCII.
The proper way to send richer content is to use a transfer encoding, and to set a
content-transfer-encodingheader. We don't yet offer any help in this regard, beyond the ability to add_optional_field(). You'll have to manage the encoding yourself. We plan to add convenience functions for this eventually (see issue #19)
- Obsolete email formats are not implemented in the parser. Therefore, it is not sufficient for parsing inbound emails if you need to recognize formats that were obsoleted in 2008.
Plans (not yet implemented)
- Support for content-transfer-encodings (unicode via Quoted Printable or Base64 or otherwise)
- Support for email headers defined in other RFCs:
- Support for RFC 6854 (updated From and Sender syntax)
- Support for all headers registered at IANA (http://www.iana.org/assignments/message-headers/message-headers.xhtml)
- Support for MIME (RFC 2045, RFC 4021, RFC 2231, RFC 6352) using mime_multipart
- Support for streaming of MIME parts from disk.
This project was inspired by the earlier email crate, but was reworked from scratch due to a number of significant differences in design, implementation and interface.
