client, err := SMTPConnect(cfg)
|

if err != nil { log.Fatal(err) }
|
|
defer client.Quit()
|
|
|

## Notas
|
|
|
|
Funcion impura — envia datos por red. El cliente debe estar autenticado (obtenido de `SMTPConnect`). BCC se incluye en RCPT TO pero no en las cabeceras MIME visibles. Los adjuntos se codifican en base64. Para HTML+texto usa `multipart/alternative`; con adjuntos usa `multipart/mixed`.
