Re: [go-nuts] Re: [ANN] Gomail v2: sending emails faster

[Tushar Desai]

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

Hello, from Russia. It would be nice to add a function for embed and attach

If those black boxes represent Go language code, please share it here by

It is impossible to understand these rectangles on my phone.

hi, i use this code, I can't make it work help

Could you tell me how to properly use your library on this code, and set an 
example for a custom dealer, so that I can access the smtp through a proxy 
(sock4, sock4a, or sock5)? is it possible? please a couple of lines of code 
for an example

func main() {

   
   ch := make(chan *gomail.Message, 10)

   // Use the channel in your program to send emails.
   m := gomail.NewMessage()
   m.SetHeader("From", "ifabion.bai...@mail.bcu.ac.uk")
   m.SetHeader("To", "t...@mail.com")

   //m.SetAddressHeader("Cc", "d...@example.com", "Dan")
   m.SetHeader("Subject", "Hello!")
   m.SetBody("text/html", "Hello Bob and Cora!")
   //m.Attach("/home/Alex/lolcat.jpg")

   ch <- m

   go func() {
  d := gomail.NewDialer("smtp-mail.outlook.com", 587, 
"ifabion.bai...@mail.bcu.ac.uk", "pwd")

  var s gomail.SendCloser

  var err error
  open := false
  for {
 select {
 case m, ok := <-ch:
if !ok {
   return
}
if !open {
   if s, err = d.Dial(); err != nil {

   }
   open = true
}
if err := gomail.Send(s, m); err != nil {
   log.Print(err)
}
 // Close the connection to the SMTP server if no email was sent in
 // the last 30 seconds.

if open {

  panic(err)
   }
   open = false
}
 }
  }
   }()

}

[go-nuts] Re: [ANN] Gomail v2: sending emails faster

[leeas via golang-nuts]

Is there a way to send an email AS a group member? Currently, I am able to 
do so via the Gmail Web Client. But I can't figure out a way to do it via 
my 3rd party client (Airmail 3), or standard Go (via net/smtp).

Hence, I was wondering if there was a way to send as a group.

Thanks very much.

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

That means the mail server is busy. Setting shorter timeout will
stress mail server even more and make things worse for everyone.

The proper way is wait, and retry (dialing), with each retry waiting twice
as long as before. So even if the remote mail server is down for a few
hours, you email can still go through eventually.

You should break that 40s up and see how long is spent on dial, and how
long is spent on send.

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 )

What do you mean by "lots of tedious manual works"?
You have to specify where shall those emails appear, (embed `` into the body),
or you can just Attach those files to the email.

[antoniosun001]

Hey Alex,

Can gomail supports embedding *a lot* of images?

From
https://godoc.org/gopkg.in/gomail.v2#Message.Embed
it seems that gomail only support embedding one image, if we embed a lot of 
them, there are still lots of tedious manual works to make it works. 

Right?

[go-nuts] Re: [ANN] Gomail v2: sending emails faster

[connelblaze]

Hey Alex, tried sending mail with gomail v2 having some ish.
here is my code:

func contact(w http.ResponseWriter, req *http.Request) {
   var s string
   var e string
   var m string
   pd := pageData{
  Title: "contact || CACCYE",
   }
   if req.Method == http.MethodPost {
  s = req.FormValue("subject")
  e = req.FormValue("mail")
  m = req.FormValue("message")

  pd.subject = s
  pd.email = e
  pd.msg = m

  cb := gomail.NewMessage()
  cb.SetHeader("From", e)
  cb.SetHeader("To", "his_m...@gmail.com", "her_m...@gmail.com")
  cb.SetHeader("Subject", s)
  cb.SetBody("text/plain", m)

  d := gomail.NewDialer("smtp.gmail.com", 587, "my_m...@gmail.com", 
"my_password")

  // Send the email to Bob, Cora and Dan.
  if err := d.DialAndSend(cb); err != nil {
 panic(err)
  }
   }

   err := tpl.ExecuteTemplate(w, "contact.gohtml", pd)
   if err != nil {
  log.Println(err)
   }
}


when i submit it outputs:

Hi Alexandre
I tried sending an email using the server settings from my outlook mailbox 
and got this error - Could you shed some light as to what this could be 
about?

[go-nuts] Re: [ANN] Gomail v2: sending emails faster

[matic]

GitHub page says "Automatic encoding of special characters". Does that mean 
if I use output from (user provided input to a 
golang.org/pkg/text/template) as body input to gomail, gomail will properly 
escape any characters that could be used to insert SMTP headers or do 
anything else that could be malicious?

[Bernard LEGAUT]

I recently switch from go 1.5.1 to go 1.6, and gomail seems to get in 
trouble. 

Anyone with the same issue ?

Thanks,
