The Example doesn't work well

[barcoyou]

I exactly follow the example in README, although the program runs properly nothing happen to me and I didn't receive any mail in my Gmail box.

In the example you just sent an e-mail to your local machine, not Google. gen_smtp e-mail server doesn't relay messages (to gmail in this instance).

[barcoyou]

Thank you for replying. Then how can I send a mail to my Gmail box?

[mworrell]

Like you did in the gen_smtp_client example, except without relay and port options.

You will need a relay if you have an ISP that blocks access to port 25 on other servers than their own smtp server. (ziggo.nl is an example of such an ISP). In that case the relay is the smtp server of your ISP.

[barcoyou]

So actually I don't need to start gen_smtp_server?

[mworrell]

Indeed - the gen_smtp_server is to receive e-mail. The gen_smtp_client is to send e-mail.

[barcoyou]

To receive email how can I setup an email account with gen_smtp_server at my local server?

[Vagabond]

gen_smtp is NOT a complete mailserver, it provides an implementation of the SMTP protocol and hooks you can use to implement the actual server (email storage, queueing, relaying, etc). It is more of a library than an application.

[barcoyou]

Thank you very much for your elucidation.

[barcoyou]

Still nothing happen by just using gen_smtp_client to send mail, as following.

Erlang R16B01 (erts-5.10.2) [source] [64-bit] [smp:8:8] [async-threads:10] [kernel-poll:false] [dtrace]

Eshell V5.10.2 (abort with ^G) 1> gen_smtp_client:send({"barcojie@gamil.com",["barcojie@gmail.com"],"Subject: testing\r\nFrom: Andrew Thompson \r\nTo: Some Dude \r\n\r\nThis is the email body"},[{relay, "smtp.gmail.com"},{port,465},{username, "barcojie@gmail.com"},{password, "mypass"}]). {ok,<0.36.0>} 2>

[barcoyou]

Could anyone help me figure out where the problem lies in?

[Vagabond]

• 1 - Try not sending email to yourself
• 2 - Try using port 25

I just tested and I was able to send email to another account fine via gmail.

[barcoyou]

Using port 25 I got error: exception error: {error,retries_exceeded, {network_failure,"smtp.gmail.com",{error,closed}}}

[Vagabond]

Does your ISP block port 25?

[mworrell]

First: try to use a better (valid) message body - to prevent the spam filters trapping your e-mail. Or test the body with another library (php/ command-line/ etc) to see if it arrives. Currently I am not sure what we are testing :)

I see that you try to relay using the gmail smtp server.

I just tested with the following, and I received the message:

Email = {
    "marc@maximonster.com",
    ["marc@maximonster.com"],
    <<"From: MW <marc@maximonster.com>\r\nTo: MW <marc@maximonster.com>\r\nSubject: Test\r\n\r\nDit is een test.">>
},
Options = [
    {ssl,true},
    {no_mx_lookups,true},
    {relay,"smtp.gmail.com"},
    {username,"marc@maximonster.com"},
    {password,"xxxx"},
    {auth,always}
],
gen_smtp_client:send_blocking(Email, Options).

(BTW in your example above you sent the message from "barcojie@gamil.com" -- I assume that is a typo in this ticket?)

[barcoyou]

With this Options, it works now. Thank you!

[mworrell]

Good to hear that it works, thanks for reporting back.
