Try to use the code from https://golang.org/pkg/net/smtp/#example_SendMail

package main

import (
    "log"
    "net/smtp"
)

func main() {
    // Set up authentication information.
    auth := smtp.PlainAuth("", "[e-mail]", "password", "mail.example.com")

    // Connect to the server, authenticate, set the sender and recipient,
    // and send the email all in one step.
    to := []string{"[e-mail]"}
    msg := []byte("To: [e-mail]
" +
        "Subject: discount Gophers!
" +
        "
" +
        "This is the email body.
")
    err := smtp.SendMail("mail.example.com:25", auth, "[e-mail]", to, msg)
    if err != nil {
        log.Fatal(err)
    }
}
