SMTP not sending emails

[Vincent-BePressure]

I am using an SMTP server with no auth, no TLS, port 25. Leantime isn't sending emails.

I edited line 80 in class.mailer.php to false, but that didn't seem to help.

There is a lack of 'test email' functionality, how do we debug? I am trying the 'forgot password' button, but can't find any logs and receive no errors.

Has anyone been able to get SMTP working or able to send emails? if so how?

Hi, Can you set debug to true in core/class.mailer.php line 76? This should give you some additional smtp output

Thank you, it looks like I was missing the from field in the email settings and I edited line 80 in class.mailer.php so emails are being sent using phpmailer instead of SMTP, which is good enough for now.

I do agree with OP @Vincent-BePressure that some kind of "Test Email" function would be great to assist in debugging.

It would be a common issue with all the different settings that various SMTP providers need.

Great feature request!

Hi - I was still not able to get email working, and now I'm confused by the configuration. I'm using docker-compose. I'm setting the following variables (relevant to email):

      LEAN_EMAIL_RETURN: '[email protected]'
      LEAN_EMAIL_USE_SMTP: true
      LEAN_EMAIL_SMTP_HOSTS: 'domain.com'
      LEAN_EMAIL_SMTP_USERNAME: '[email protected]'
      LEAN_EMAIL_SMTP_PASSWORD: 'somepassword'
      LEAN_EMAIL_SMTP_SECURE: 'SSL'
      LEAN_EMAIL_SMTP_PORT: 465

However I'm confused whether those are the right variables names given that this mentions variables like SMTP_ENABLE, SMTP_HOST, etc. Am I even setting the right variables? How could I enable some debug to get more information in the logs? Etc.

(The way I'm testing now is the "forgot password" link, and after filling in the email, the website times out with 504 bad gateway error. Nothing relevant appears in the logs.)

Hm, seems like I fixed it by changing LEAN_EMAIL_SMTP_PORT: 465 to 587. This is counterintuitive because I'm using mailcow and the manual configuration page states that for SSL one should use port 465. But, it works, after all.

This worked for me as well but it feels super hacky.

Hi, I don't receive any email and I don't know how I can debug this ?

My configuration :

    /* Email */
    public $email = '[email protected]';		//Return email address
    public $useSMTP = true;					//Use SMTP? If set to false, the default php mail() function will be used
    public $smtpHosts = 'mail.infomaniak.com';		//SMTP host
    public $smtpAuth = true;					//SMTP use user/password authentication
    public $smtpUsername = '[email protected]';	//SMTP username
    public $smtpPassword = 'xxxxxxxxxxxx';	                //SMTP password
    public $smtpAutoTLS = true;				//SMTP Enable TLS encryption automatically if a server supports it
    public $smtpSecure = 'SSL';					//SMTP Security protocol (usually one of: TLS, SSL, STARTTLS)
    public $smtpSSLNoverify = true;				//SMTP Allow insecure SSL: Don't verify certificate, accept self-signed, etc.
    public $smtpPort = '465';					//Port (usually one of 25, 465, 587, 2526)

I've tried many configuration without success and I haven't anything in the log file.
In my DNS I have configured SPF, DKIM and DMARC (My IP server is in my SPF txt).
I made a light script PHP to see if the was a problem with my DNS configuration or my server (Infomaniak) but it works well with Leantime librairies.
Here is the script I use in "public" :

<?php

//Import PHPMailer classes into the global namespace
//These must be at the top of your script, not inside a function
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\SMTP;
use PHPMailer\PHPMailer\Exception;

//Load Composer's autoloader
require '../vendor/autoload.php';

//Create an instance; passing `true` enables exceptions
$mail = new PHPMailer(true);

try {
    //Server settings
    $mail->SMTPDebug = SMTP::DEBUG_SERVER;                      //Enable verbose debug output
    $mail->isSMTP();                                                            //Send using SMTP
    $mail->Host       = 'mail.infomaniak.com';                      //Set the SMTP server to send through
    $mail->SMTPAuth   = true;                                           //Enable SMTP authentication
    $mail->Username   = '[email protected]';                 //SMTP username
    $mail->Password   = 'xxxxxxxxxxxx';                               //SMTP password
    $mail->SMTPSecure = PHPMailer::ENCRYPTION_SMTPS;            //Enable implicit TLS encryption
    $mail->Port       = 465;                                    //TCP port to connect to; use 587 if you have set `SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS`

    //Recipients
    $mail->setFrom('[email protected]', 'Mailer');
    $mail->addAddress('[email protected]', 'Surname');     //Add a recipient
    $mail->addReplyTo('[email protected]', 'Information');

    //Content
    $mail->isHTML(true);                                  //Set email format to HTML
    $mail->Subject = 'Here is the subject';
    $mail->Body    = 'This is the HTML message body <b>in bold!</b>';
    $mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

    $mail->send();
    echo 'Message has been sent';
} catch (Exception $e) {
    echo "Message could not be sent. Mailer Error: {$mail->ErrorInfo}";
}
?>

If you have any other way to find how to solve my problem, it would be great ;o)

Following is my experience, hope it would be helpful for someone:

I am using Docker Desktop on Windows Server 2022.
I have to add DNS Configuration in the settings, otherwise Leantime Container can not resolve the domain in it's Container.
After I made this change, SMTP works OK!
