Functions

func Run

func Run(cfg Config, w io.Writer, send Sender) error

Run composes the message. If w is non-nil the composed message is written to it (the -o path); otherwise it is handed to send.

Types

type Config

type Config struct {
	From       string
	To         []string
	Subject    string
	Body       string
	SMTPServer string
}

Config holds the fields needed to compose a message. Body is the already-read message body (main reads the -b file); SMTPServer is the host part of the server address ("" if a composed-message writer is used instead).

func (Config) Validate

func (c Config) Validate() error

Validate reports whether the required fields are present.

type Sender

type Sender func(msg *mail.Message) error

Sender sends a composed message. It is injected so Run can be tested without touching the network; the default sender talks SMTP.

func DefaultSender

func DefaultSender(server string) Sender

DefaultSender sends the message via SMTP to server:25 with no auth.
