// send mail
func SendMail(subject string, message string, from *mail.Address, to []string, smtpConfig SmtpConfig, isHtml bool) error {
auth := smtp.PlainAuth(
"",
smtpConfig.Username,
smtpConfig.Password,
smtpConfig.Host,
)
contentType := "text/plain"
if isHtml {
contentType = "text/html"
}
msg := fmt.Sprintf("To: %s\r\nFrom: %s\r\nSubject: %s\r\nContent-Type: %s; charset=UTF-8\r\n\r\n%s",
strings.Join(to, ","), from.String(), subject, contentType, message)
return smtp.SendMail(smtpConfig.Addr, auth, from.Address, to, []byte(msg))
}
