Configuration method for sending emails through gmail with phplist and phpmailer (combined use)

This article describes the configuration method of phplist and phpmailer sending emails through gmail. Share it for your reference, as follows:

Generally speaking, as long as you are not using gmail mailbox, then use phplist to send emails as follows:A detailed summary of the phplist configuration method of PHP's email mass sending system》Configuration is enough. But if you are as unfortunate as me and must use gmail such as SSL verification, then congratulations, my misfortune has become your luck now. After several days of attempts, I finally successfully combined gmail with phplist. I will share my experience here, hoping it will be useful to all comrades in my ordinary situation. In addition, the core of phplist is phpmailer, and the solution I proposed is mainly around phpmailer, so those who need to use phpmailer to send emails through gmail and cannot succeed can also refer to my method.

First, according toA detailed summary of the phplist configuration method of PHP's email mass sending systemThe configuration method in 》 sends emails through gmail. When sending test emails, phplist will report the sending email failure. There will be an error message in the event log (eventlog) "Mailer Error: The following From address failed:...", which says there is a problem with the sender's address. Is it because I have already connected to the SMTP server, but there are problems during the email sending? You can use one method to test whether you are connected to the SMTP server: I deliberately filled in the mailbox account password in the file, but the same error was reported when sending the test email. It seems that I was not connected to the SMTP server at all. This phplist error report is too...

If you know that you are not connected to the SMTP server, it means that the problem occurs at the core of phplist sending emails - another famous open source software, phpmailer.

I checked the information of phpmailer sending gmail emails on the Internet and found that people said that the old version of phpmailer does not support SSL verification and cannot connect to Gmail's SMTP server. This problem has been solved in the new version of phpmailer.

Open lists/admin/phpmailer/ and found that the latest version of phplist comes with phpmailer version 1.73, which was released in 2005, and is indeed not new. So I went to the phpmailer official website to download the latest 5.1.

I want to first study how the new version of phpmailer solves the problem of SSL verification, so I looked at some of the documentation it comes with and happened to find that there is a use_gmail.txt under PHPMailer_v5.1/docs. It seems that the official attaches great importance to the gmail problem and has specially released a demo for reference. When you open it, it is indeed a complete php page file. You can basically use it by modifying the file extension, email username and password. However, if you only modify it like this, an error will be reported when accessing the test page. I don’t know why the official demo will have such an error. It will actually call an undefined function, and there are some unnecessary components. We just want to test whether we can send emails normally, so I modified them to:

<?php
    // example on using PHPMailer with GMAIL
    include("");
    include(""); // note, this is optional - gets called from main class if not already loaded
    $mail       = new PHPMailer();
    $body       = "test";
    $mail->IsSMTP();
    $mail->SMTPAuth  = true;         // enable SMTP authentication
    $mail->SMTPSecure = "ssl";         // sets the prefix to the servier
    $mail->Host    = "";   // sets GMAIL as the SMTP server
    $mail->Port    = 465;          // set the SMTP port
    $mail->Username  = "myname@"; // GMAIL username
    $mail->Password  = "mypassword";      // GMAIL password
    $mail->From    = "myname@";
    $mail->FromName  = "Webmaster";
    $mail->Subject  = "This is the subject";
    $mail->AltBody  = "This is the body when user views in plain text format"; //Text Body
    $mail->WordWrap  = 50; // set word wrap
    $mail->MsgHTML($body);
    $mail->AddReplyTo("myname@","Webmaster");
    $mail->AddAddress("myname@","First Last");
    $mail->IsHTML(true); // send as HTML
    if(!$mail->Send()) {
     echo "Mailer Error: " . $mail->ErrorInfo;
    } else {
     echo "Message has been sent";
    }
?>

It turned out that I still reported an error when accessing this page. It was really helpless. How could the demo given by the official cannot run?

At this moment, I suddenly remembered that there is a file named Note_for_SMTP_debugging.txt under PHPMailer_v5.1/docs. I am worried about not being able to connect to the SMTP server. Why not take a look at the debugging methods provided in it.

After opening the file and reading the first line, my eyes lit up. This is exactly what I need! In fact, the usage method is very simple, as long as it is

$mail->IsSMTP();

Front insertion

$mail->SMTPDebug = 1;

This allows you to get more detailed error information while reporting an error. What a good thing^_^

After modifying this, I got a more detailed explanation when accessing the page - "SMTP -> ERROR: Failed to connect to server: Unable to find the socket transport "ssl" - did you forget to enable it when you configured PHP? (28593608)".

So that's it, so I opened my php configuration file (C://Windows/) to search for ssl, and sure enough, I found an extension about ssl

;extension=php_openssl.dll

It was not opened. Remove the ";" used for commenting in front of it, then restart the server, and visit the test page again to use_gmail.php, and the same error message is still the same.

There is no way. I checked the article about php and apache's SSL configuration online and found that it is not enough to just enable the ssl extension module. You also need to configure openssl. The configuration method in a Windows environment is very simple - find the sum in the php installation directory and copy the two into the system32 directory under Windows (it is still necessary to enable extension=php_openssl.dll). Of course, comrades who do not want to "pollute" the system32 directory can use the method of modifying environment variables, just let and under the system path. (If you are not using a Windows operating system, please go online to find the method to configure SSL for your operating system, which should not be difficult to find)

This time I visited use_gmail.php again and found that it could be sent successfully!

On this basis, our phplist problem can also be solved: use the sum in the new version of phpmailer to overwrite the corresponding files in lists/admin/phpmailer, and then modify the about 36 lines in lists/admin/

$this->SMTPAuth = true;
$this->Helo = getConfig("website");
$this->Host = PHPMAILERHOST;

for:

$this->IsSMTP();            # Add
$this->SMTPAuth = true;
$this->SMTPSecure = "ssl";       # Add
$this->Helo = getConfig("website");
$this->Host = PHPMAILERHOST;
$this->Port = 465            # Add

The default port number of phpmailer is 25, which is the port number of most SMTP servers, but the port number used by gmail is 465, so you need to reset it.
