Hi, I set a timeout of 20 sec for the Dialer, but the DialAndSend continued beyond the timeout and sent email after 27sec.
code: dialer = gomail.NewDialer("smtp.mailtrap.io", 587, u, p) dialer.Timeout = 20*time.Second start := time.Now() if err = dialer.DialAndSend(m); err != nil { err = fmt.Errorf("sendEmail: sending email to %s; %s", u.email, err) return } elapsed := time.Since(start) lgr.Trace().Msgf("EML %11.6fms", float64(elapsed)/float64(time.Millisecond)) Log message: 2/28 06:41:00.325 TRC EML 27604.141065ms remote=172.19.0.1 On Friday, August 25, 2017 at 9:47:12 AM UTC+5:30 Antonio Sun wrote: > You should break that 40s up and see how long is spent on dial, and how > long is spent on send. > > On Thu, Aug 24, 2017 at 9:41 PM, <yhj7...@163.com> wrote: > >> Thank you very much for your reply.
