Simple Usage

oCfg := SMTPClientConfig{
  Server:   "mx.test.com",
  Port:     587,
  Username: "test@test.com",
  Password: "...",
  Mode:     ModeSTARTTLS,
  // SMTPLog:  "-",  // note: uncomment to log SMTP session to STDOUT
}

oEmail := NewEmail()
oEmail.From    = "test@test.com"
oEmail.To      = []string{"test_receiver@eggplant.pro"}
oEmail.Subject = "Test Message"
oEmail.Text    = []byte("Whoomp there it is!")

E := oCfg.SimpleSend(oEmail)
if E != nil { return E }

Reasons for Fork

This is a fork of https://github.com/jordan-wright/email

• ripped out connection pooling (sending via long-term connections to SMTP servers has not been reliable)
• condensed multiple Send... methods into NewClient() & Send() to
  • provide a more generic way of establishing unauthenticated, SSL, and STARTTLS connections
  • send multiple messages from within a single established SMTP session
  • make direct use of outside net.Conn interfaces, so as to set dial and I/O deadlines
• added LoginAuth authentication interface for use with Office 365
• added TextprotoLogged for full logging of SMTP traffic

Testing

To run unit tests, add the proper credentials to email_test_settings.json for accounts you choose to test with. Examples for O365, GMAIL, & CUSTOM have been provided.
