Hi guys,

I have the following issue:

When I try to send an email I get a 500 error
In the logs and debug mod it's saying it's caused by /­vendor/­swiftmailer/­swiftmailer/­lib/­classes/­Swift/­Transport/­Esmtp/­Auth/­NTLMAuthenticator.php:303
The following script is showing in the debug mode:

protected function getDomainAndUsername($name)
  {
    if (strpos($name, '\\') !== false) {
            return explode('\\', $name);
       }

       list($user, $domain) = explode('@', $name);

       return array($domain, $user);

This is my mail.php config:

<?php

return array(

    */

    'pretend' => false,

);

For the username I even tried the email adres.
The email account does not need a password

I hope you guys can help me.

[snipe]

Does it happen ever time you try to send mail? What are you doing to trigger it?

[IxFail]

Yes it is happing every time Try to send a mail.

I activate that users get a mail when an asset is checked in or out of their name. When I check an asset in or out I get the 500 error in about 6 seconds.

[snipe]

Do all of your users have email addresses in your system?

[IxFail]

Yes all users have an email adress.

[snipe]

It looks like it's trying to use prhc.systeembeh somewhere. Is that a username, a user's email address, or what?

[IxFail]

prhc.systeembeh should be prhc.systeembeheer as prhc.systeembeheer is in the mail.php as the username for smtp.
Could the problem be caused by the . Between prhc and systeembeheer?

[snipe]

I think it's the no password thing that's causing the problem. See this bit in the stack trace:

/var/www/snipeit/vendor/swiftmailer/swiftmailer/lib/classes/Swift/Transport/Esmtp/AuthHandler.php(176): Swift_Transport_Esmtp_Auth_NTLMAuthenticator->authenticate(Object(Swift_SmtpTransport), 'prhc.systeembeh...', '')

[IxFail]

Tomorrow I will enter my own mail credentials(which requires a password) because the prhc.systeembeheer does not has a password. And I will check if the error still pops-up

[IxFail]

Okay the Undefined offset: 1 error was indeed caused by the empty password field, I created a special service account that is allowed to send from the mailbox and Tadaa. I can send mails with Snipe-IT.

Thank you for your help @snipe

[hoaimv]

Dear snipe ,IxFail
Thanks to your support in this case, you can guide in more detail what to fix to be able to fix this error.
I have the same situation as you
How do I fix it with the code below
_Transport_SmtpAgent $agent to read/write
*/
public function afterEhlo(Swift_Transport_SmtpAgent $agent)
{
if ($this->username) {
$count = 0;
$errors = [];
foreach ($this->getAuthenticatorsForAgent() as $authenticator) {
if (in_array(strtolower($authenticator->getAuthKeyword()), array_map('strtolower', $this->esmtpParams))) {
++$count;
try {
if ($authenticator->authenticate($agent, $this->username, $this->password)) {
return;
}
} catch (Swift_TransportException $e) {
// keep the error message, but tries the other authenticators
$errors[] = [$authenticator->getAuthKeyword(), $e->getMessage()];
}
}
}

        $message = 'Failed to authenticate on SMTP server with username "'.$this->username.'" using '.$count.' possible authenticators.';
        foreach ($errors as $error) {
            $message .= ' Authenticator '.$error[0].' returned '.$error[1].'.';
        }
        throw new Swift_TransportException($message);
    }
}

/**
 * Not used.
 */
public function getMailParams()
{
    return [];
}

/**
 * Not used.
 */
public function getRcptParams()
{
    return [];
}

Thanks you so much

Hi @hoaimv ,

This issue was solved 4 years ago, so my memory is a little rusty, but if I read my own replies; I just added a SMTP account that was using a password.
'username' => 'PUT HERE A SMTP USERNAME',

'password' => 'PUT HERE THE USER PASSWORD FOR SMPT',

In Snipe version 2.1.0-41 the password was mandatory even if the SMTP user could send mail without a password.

Dear IxFail
Can you please send me 2 files mail.php config & AuthHandler.php has successfully run help
Thank You so much

[IxFail]

@hoaimv,

Sorry I cant do that, I don't work for the company that used Snipe-IT anymore +I haven't used Snipe-It for atleast 3 years.

I wish you the best in finding a solution with your problem.

[hoaimv]

Dear snipe ,IxFail
when using snipe it when checking in and check out only send emails that have 2 layers security opened
Mail with 2-layer security off does not receive mail
Thanks to your support
