Constants

const InternalIDDomain = `protonmail.internalid`

InternalIDDomain is used as a placeholder for reference/message ID headers to improve compatibility with various clients.

Variables

var (
	ErrDecryptionFailed = errors.New("message could not be decrypted")
	ErrNoSuchKeyRing    = errors.New("the keyring to decrypt this message could not be found")
)

Functions

func BuildRFC822

func BuildRFC822(kr *crypto.KeyRing, msg proton.Message, attData [][]byte, opts JobOptions) ([]byte, error)

func BuildRFC822Into

func BuildRFC822Into(kr *crypto.KeyRing, msg proton.Message, attData [][]byte, opts JobOptions, buf *bytes.Buffer) error

func HeaderLines

func HeaderLines(header []byte) [][]byte

HeaderLines returns each line in the given header.

func SanitizeMessageDate

func SanitizeMessageDate(msgTime int64) time.Time

SanitizeMessageDate will return time from msgTime timestamp. If timestamp is not after epoch the RFC822 publish day will be used. No message should realistically be older than RFC822 itself.

Types

type Attachment

type Attachment struct {
	Header      mail.Header
	Name        string

}

type Body

type Body string

type JobOptions

type JobOptions struct {
	IgnoreDecryptionErrors bool // Whether to ignore decryption errors and create a "custom message" instead.
	SanitizeDate           bool // Whether to replace all dates before 1970 with RFC822's birthdate.
	AddInternalID          bool // Whether to include MessageID as X-Pm-Internal-Id.
	AddExternalID          bool // Whether to include ExternalID as X-Pm-External-Id.

}

func Parse

func Parse(r io.Reader) (m Message, err error)

Parse parses an RFC822 message.

func ParseWithParser

func ParseWithParser(p *parser.Parser) (m Message, err error)

ParseWithParser parses an RFC822 message using an existing parser.
