go get gopkg.in/gomail.v1
package main

)
func main() {
msg := gomail.NewMessage()
msg.SetHeader("From", "[email protected]")
msg.SetHeader("To", "[email protected]", "[email protected]")
msg.SetAddressHeader("Cc", "[email protected]", "Dan")
msg.SetHeader("Subject", "Hello!")
msg.SetBody("text/html", "Hello <b>Bob</b> and <i>Cora</i>!")
f, err := gomail.OpenFile("/home/Alex/lolcat.jpg")
if err != nil {
panic(err)
}
msg.Attach(f)
// Send the email to Bob, Cora and Dan
mailer := gomail.NewMailer("smtp.example.com", "user", "123456", 587)
if err := mailer.Send(msg); err != nil {

}If you get this error it means the certificate used by the SMTP server is not
considered valid by the client running Gomail. As a quick workaround you can
bypass the verification of the server's certificate chain and host name by using
SetTLSConfig:
mailer := gomail.NewMailer("smtp.example.com", "user", "123456", 587, gomail.SetTLSConfig(&tls.Config{InsecureSkipVerify: true}))
Note, however, that this is insecure and should not be used in production.
If you get this error, you should try using the LOGIN authentication mechanism:
addr := "smtp.example.com:587"
auth := gomail.LoginAuth("username", "password", "smtp.example.com")
mailer := gomail.NewCustomMailer(addr, auth)
