I have created a go application that sends an email using net/smtp and PlainAuth. And everything is working fine. But when I deploy this same code on the google app engine it is not sending. If I serve using goapp serve it work locally. Below is the code:
func sendMail(body string, subject string) {
var err error
var doc bytes.Buffer
auth := smtp.PlainAuth("",
"from@gmail.com",
"********",
"smtp.gmail.com")
parameters := &SmtpTemplateData{
"from@gmail.com",
"to@gmail.com",
"Subject",
body,
}
buffer := new(bytes.Buffer)
template := template.Must(template.New("emailTemplate").Parse(emailScript()))
template.Execute(buffer, parameters)
t := template.New("emailTemplate1")
t, err = t.Parse(emailTemplate)
if err != nil {
fmt.Println("error trying to parse mail template")
}
err = t.Execute(&doc, parameters)
smtp.SendMail(
"smtp.gmail.com:587",
auth,
"from@gmail.com",
[]string{"to@gmail.com"},
doc.Bytes(),
)
}
