Moodle smtp error could not authenticate

That server is accessible to me; your ISP is blocking your outbound SMTP, as the docs say.

Can you please elaborate i am not able to get you?

If I do telnet rsixchange.ramco.com 25, it connects correctly. If you do the same from your server, it probably will not work. This procedure is described in the troubleshooting guide. It means your hosting provider is preventing you form connecting to the mail server, so it’s nothing to do with your code.

ok.. let me check in my server.. please be connected and help me to rectify this issue

There’s really nothing I can do — ask your hosting provider’s support services.

Hi marcus, telnet is connected in my server too. but still i am getting the error. i have tested a sample test mail from the server too. it is working. but through moodle i am not able to send or receive mail.

now i am getting this error

Your mail server is out of spec — the AUTH capability line should be followed by a list of the authentication types it supports — but it doesn’t list any so you can’t authenticate. For example, here’s how gmail responds:

250-smtp.gmail.com at your service, [88.184.221.3]
250-SIZE 35882577
250-8BITMIME
250-AUTH LOGIN PLAIN XOAUTH2 PLAIN-CLIENTTOKEN OAUTHBEARER XOAUTH
250-ENHANCEDSTATUSCODES
250-PIPELINING
250-CHUNKING
250 SMTPUTF8

Another strange thing is that I get different capabilities listed on your server — though it’s normal to require STARTTLS before allowing AUTH:

telnet rsixchange.ramco.com 25
Trying 14.141.0.163...
Connected to rsixchange.ramco.com.
Escape character is '^]'.
220 ramcomail1.ramco.com ESMTP
EHLO localhost
250-ramcomail1.ramco.com
250-8BITMIME
250-SIZE 104857600
250 STARTTLS

It might be worth trying port 587 instead of 25 in case they don’t accept message submission on port 25. Beyond that I suggest talking to your support services.

I have got some sample code
$mail = new PHPMailer();

$mail->IsSMTP();
$mail->SMTPDebug = 2;
$mail->Host = «smtp.live.com»;
$mail->Port = 25;
$mail->SMTPAuth = true;
$mail->Username = «MY USERNAME (hotmail)»;
$mail->Password = «MY PASSWORD (hotmail)»;
but i am not sure which php file i need to mention.. either in phpmailer.php or smtp.php
can you please suggest

I mean try this:

You should also set:

$mail>-SMTPSecure = 'tls';

i am sorry my doubt is where to write this code ?

Do i need to write the code in smtp.php ?

Hi marcus, in my server port number 25 only i am able to send and receive the messages.

this is my configuration settings that i got from the support services
and my error as follows :

In normal telnet i am able to send mail, through php i am able to send mail, through backend sql server i am able to send the DBmailer.

only through moodle i am not able to do it.

As I said, their server response is broken. You could try disabling authentication, with SMTPAuth = false.

thanks for the reply sir. Now i am getting the below error.

Can you please help me in this.. i have updated the certificate and mentioned in my php.ini file
openssl cafile/curl info but still i am getting this error

You need to figure out why the verification is failing. This is likely to be one of 3 things:

• The name on the certificate (what the server says in response to EHLO) does not match the name in your Host property.
• The certificate has expired.
• You don’t have a matching CA certificate in your operating system’s certificate store.

The first of these you can check just by comparing the names. The other two you can check using the openssl s_client commands shown in the troubleshooting guide.

thanks for the response.. do i need to generate the certificate in the name of my host i.e either server IP address or in the system name or the host i mentioned learningsupport.ramco.com

The name of the server you’re connecting from doesn’t matter, nor does this have anything to do with your own site’s certificate – it’s all about the name of the mail server you’re connecting to, and unless that’s your own mail server, you probably don’t have much control over that.

Thanks for the support my smtp mailer is working

I encountered this problem. To get it working, I had to go to myaccount.google.com -> «Sign-in & security» -> «Apps with account access», and turn «Allow less secure apps» to «ON» (near the bottom of the page).

Alternatively you can follow this direct link to these settings

Try this instead :

$Correo->Username = «foo@gmail.com»;

I tested it and its working perfectly without no other change

I received the same error and in mycase it was the password. My password has special characters.

If you supply the password without escaping the special characters the error will persist.

E.g $mail->Password = " por$ch3"; is valid but will not work using the code above .

The solution should be as follows: $mail->Password = "por$ch3";

Note the Backslash I placed before the dollar character within my password.
That should work if you have a password using special characters

answered Aug 1, 2012 at 9:57

Because Allow less secure apps is no longer available

The solution was to enable 2-step verification and generate app password

select mail and computer from the list then click generate

copy the code shown in the box and replace your google password with your app password it works like a charm.

I experienced the same error when configuring the WP-Mail-SMTP plugin in WordPress.

The problem would persist even when I have ‘triple checked’ the settings and login credentials, and am able to log in manually using a browser.

There’s a list of steps you can take to fix this.

1. Create a new password for the Gmail account you want to use
2. Enable less secure apps in Google Security settings
3. Use the Display Unlock Captcha page to give your app or website permission to sign in to Gmail. Click Continue or follow the instructions.
4. Sign in using the app or website. The smtp settings that work for me are 1) SMTP Host: smtp.gmail.com 2) SMTP port: 587 3) Encryption: TLS 4) Authentication: SMTP authentication 5) Username: example@gmail.com 6) Password: examplesecret

my solution is:

1. change gmail password
2. on gmail «Manage your google Account» > Security > Turn on 3rd party app Access
3. This the new step that i discover by UnlockingCaptcha that told in this site, the exact site is https://accounts.google.com/b/0/DisplayUnlockCaptcha, but maybe you want to read the former site first.

That all, hope it works for you

If you still face error in sending email, with the same error message. Try this:

$mail->SMTPSecure = 'tls';
$mail->Host = 'smtp.gmail.com';

just Before the line:

$send = $mail->Send();

or in other sense, before calling the Send() Function.

Tested and Working.

The other post is correct to resolve the issue but doesn’t address how to do it if the 2-step-verification is turned on. The option to allow the less secure apps is NOT available then. Here is an answer to how to do it:

a. Go to the URL of `https://myaccount.google.com/` and click `Sing-in and security`

b. Click on the app password. 

You will reach a page like this,

c. Create name of your app and generate a password for the respective app.  

d. Use that password acquired here inside the app.

This should resolve the issue.
