Functions

func NewLoginAuth

func NewLoginAuth(username, password string) smtp.Auth

NewLoginAuth returns an Auth that implements the LOGIN authentication mechanism as defined in RFC 4616.

Types

type LoginAuth

type LoginAuth struct {
	// contains filtered or unexported fields
}

LoginAuth is an Auth that implements the LOGIN authentication mechanism as defined in RFC 4616.

func (*LoginAuth) Next

func (a *LoginAuth) Next(fromServer []byte, more bool) ([]byte, error)

Next continues the authentication. The server has just sent the fromServer data. If more is true, the server expects a response, which Next should return as toServer; otherwise Next should return toServer == nil. If Next returns a non-nil error, the SMTP client aborts the authentication attempt and closes the connection.

func (*LoginAuth) Start

func (a *LoginAuth) Start(server *smtp.ServerInfo) (string, []byte, error)

Start begins an authentication with a server. It returns the name of the authentication protocol and optionally data to include in the initial AUTH message sent to the server. It can return proto == "" to indicate that the authentication should be skipped. If it returns a non-nil error, the SMTP client aborts the authentication attempt and closes the connection.
