PHPMailer - SMTP ERROR: Password command failed wh

问题:

I have used phpmailer() concept to send mail to users from my shared server using php script, but I\'m not able to send even though everything is right in my script according to phpmailer code.

My code like this:

  $message = \" This is testing message from my server\";

  $mail = new PHPMailer(); // create a new object
  $mail->IsSMTP(); // enable SMTP
  $mail->Host = \"smtp.gmail.com\";
  $mail->SMTPDebug = 1; // debugging: 1 = errors and messages, 2 = messages only
  $mail->SMTPAuth = true; // authentication enabled
  $mail->SMTPSecure = \'ssl\'; // secure transfer enabled REQUIRED for GMail
  $mail->Port = 465; // or 587
  $mail->IsHTML(true);
  $mail->Username = \"[e-mail]\"; // My gmail username
  $mail->Password = \"************\"; // My Gmail Password
  $mail->SetFrom(\"[e-mail]\");
  $mail->Subject = \"Test Mail from my Server\";
  $mail->Body = $message;
  $mail->AddAddress($email);
   if($mail->Send())
      {
    print json_encode(\"SUCCESS\");
}
else
{
    echo \"Mailer Error: \" . $mail->ErrorInfo;

}

Note: I have used \" GMail \" as my SMTP server and SMTPSecure is \" ssl \" and port is \"465\" and username & passwords are my GMail username & password

I used VPS shared server and I kept my php script on that server.

I think there is no problem in my php script and I don\'t know why it doesn\'t work.

I got the ERROR like this.

  2014-02-21 12:30:11   CLIENT -> SERVER: EHLO jkcorporates.com

  2014-02-21 12:30:11   CLIENT -> SERVER: QUIT
  \" The ERROR is  \"  SMTP connect() failed.

Please give some solution for that.
Thanks in Advance.

Remember: I use Shared Server Name \'VPS.mydomain.com\' and I want to use GMail as my SMTP server to send mail to users.

A bit late, but perhaps someone will find it useful.

Links that fix the problem (you must be logged into google account):

https://security.google.com/settings/security/activity?hl=en&pli=1

https://www.google.com/settings/u/1/security/lesssecureapps

https://accounts.google.com/b/0/DisplayUnlockCaptcha

Some explanation of what happens:

This problem can be caused by either \'less secure\' applications trying to use the email account (this is according to google help, not sure how they judge what is secure and what is not) OR if you are trying to login several time in a row OR if you change countries (for example use VPN, move code to different server or actually try to login from different part of the world).

To resolve I had to: (first time)

• login to my account via web
• view recent attempts to use the account and accept suspicious access: THIS LINK
• disable the feature of blocking suspicious apps/technologies: THIS LINK

This worked the first time, but few hours later, probably because I was doing a lot of testing the problem reappeared and was not fixable using the above method. In addition I had to clear the captcha (the funny picture, which asks you to rewrite a word or a sentence when logging into any account nowadays too many times) :

• after login to my account I went HERE
• Clicked continue

Hope this helps.

Use this:

https://www.google.com/settings/u/1/security/lesssecureapps
https://accounts.google.com/b/0/DisplayUnlockCaptcha
https://security.google.com/settings/security/activity?hl=en&pli=1

this link allow acces to google account

UPDATE 19-05-2017:

These url you must to visit from the IP address that will be send email

回答3:

As others already suggested, you can enable the \"less secure\" applications or you can simply switch from ssl to tls:

$mailer->Host = \'tls://smtp.gmail.com\';
$mailer->SMTPAuth = true;
$mailer->Username = \"[e-mail]\";
$mailer->Password = \"***\";
$mailer->SMTPSecure = \'tls\';
$mailer->Port = 587;

When using tls there\'s no need to grant access for less secure applications, just make sure, IMAP is enabled.

Solved the problem - PHPMailer - SMTP ERROR: Password command failed when send mail from my server

    require_once(\'class.phpmailer.php\');
    include(\"class.smtp.php\"); 
    $nameField = $_POST[\'name\'];
    $emailField = $_POST[\'email\'];
    $messageField = $_POST[\'message\'];
    $phoneField = $_POST[\'contactno\'];
    $cityField = $_POST[\'city\'];

$mail = new PHPMailer(true); // the true param means it will throw exceptions on errors, which we need to catch

$mail->IsSMTP(); // telling the class to use SMTP

$body .= $nameField;

try {
     //$mail->Host       = \"mail.gmail.com\"; // SMTP server
      $mail->SMTPDebug  = 2;                     // enables SMTP debug information (for testing)
      $mail->SMTPAuth   = true;                  // enable SMTP authentication
      $mail->SMTPSecure = \"ssl\";                 // sets the prefix to the servier
      $mail->Host       = \"smtp.gmail.com\";      // sets GMAIL as the SMTP server
      $mail->Port       = 465;   // set the SMTP port for the GMAIL server
      $mail->SMTPKeepAlive = true;
      $mail->Mailer = \"smtp\";
      $mail->Username   = \"[e-mail]\";  // GMAIL username
      $mail->Password   = \"********\";            // GMAIL password
      $mail->AddAddress(\'[e-mail]\', \'abc\');
      $mail->SetFrom(\'[e-mail]\', \'def\');
      $mail->Subject = \'PHPMailer Test Subject via mail(), advanced\';
      $mail->AltBody = \'To view the message, please use an HTML compatible email viewer!\'; // optional - MsgHTML will create an alternate automatically
      $mail->MsgHTML($body);
      $mail->Send();
      echo \"Message Sent OK</p>\\n\";
      header(\"location: ../test.html\");
} catch (phpmailerException $e) {
      echo $e->errorMessage(); //Pretty error messages from PHPMailer
} catch (Exception $e) {
      echo $e->getMessage(); //Boring error messages from anything else!
}

Important:

Go to google Setting and do \'less secure\' applications enables. It will work. It Worked for Me.

I face the same problem, and think that I do know why this happens.

The gmail account that I use is normally used from India, and the webserver that I use is located in The Netherlands.

Google notifies that there was a login attempt from am unusualy location and requires to login from that location via a web browser.

Furthermore I had to accept suspicious access to the gmail account via https://security.google.com/settings/security/activity

But in the end my problem is not yet solved, because I have to login to gmail from a location in The Netherlands.

I hope this will help you a little! (sorry, I do not read email replies on this email address)

If you are G Suit user it can be solved by Administrator

1. Go to your Admin panel
2. Type in top search bar «Security» (Select Security with Shield icon)
3. Open Basic settings
4. Goto Less secure apps section
5. Press: Go to settings for less secure apps ››

And now select one of Radio Button a) Disable access to less secure apps for all users (Recommended) b) Allow users to manage their access to less secure apps c) Enforce access to less secure apps for all users (Not Recommended)

Usually It does not working because of a)! And will start working immediately with c) option. b) – option will need more configuration for each user in GSuit

Hope it helps

This error is due to more security features of gmail..

Once this error is generated...Please login to your gmail account..there you can find security alert from GOOGLE..follow the mail...check on click for less secure option..Then try again phpmailer..

For those who are still unable to get it working, try the following in addition to the method provided by @CallMeBob.

PHP.ini

1. Go to C:\\xampp\\php , edit php.ini file with notepad.
2. Press CTRL+F on your keyboard, input sendmail_path on the search bar and click Find Next twice.
3. Right now, you should be at the [mail munction] section.

Remove the semicolon for this line: sendmail_path = \"\\\"C:\\xampp\\sendmail\\sendmail.exe\\\" -t\"
Add a semicolon for this line: sendmail_path=\"C:\\xampp\\mailtodisk\\mailtodisk.exe\"

SendMail.ini

• Go to C:\\xampp\\sendmail, edit sendmail.ini file with notepad
• Change the following:
  

• smtp_server=smtp.gmail.com
• smtp_port=465
• auth_username=[e-mail]
• auth_password=your-gmail-password
• force_sender=[e-mail]

Note:
** smtp_port must tally with your those written in your php code.
** Remember to change your-gmail-username and your-gmail-password to whichever account you are using.
**

Hope this helps! :)

Your mail won\'t be sent online unless you complete the two-step verification for your g-mail account and use that password.
