Thanks very much.

But, what I mean of setting timeout is giving up this sending, and try to 
send another email

Thank you very much for your reply. However, in my code, it spent 40s to 
send email. 

Here is the code:

now := time.Now()
msg := gomail.NewMessage()
//the element of msg is abridged
dial := gomail.Dialer{Host: "127.0.0.1", Port: 25}
dial.TLSConfig = {InsecureSkipVerify: true}
if err := dial.DialAndSend(msg); err != nil {
log.Fatal("failed to send email", err)
} else {
timeSpent := fmt.Sprintf("%.3f s", time.Since(now).Seconds())
fmt.Println("time to spend in sending email", timeSpent )
}

Hi, 
Could you show me a method to set timeout when send a email?
Regards.
