I add the following code to the functions.php file.
add_action( \'phpmailer_init\', \'my_phpmailer_example\' );
function my_phpmailer_example( $phpmailer ) {
$phpmailer->isSMTP();
$phpmailer->Host = SMTP_HOST;
$phpmailer->SMTPAuth = SMTP_AUTH;
$phpmailer->Port = SMTP_PORT;
$phpmailer->Username = SMTP_USER;
$phpmailer->Password = SMTP_PASS;
$phpmailer->SMTPSecure = SMTP_SECURE;
$phpmailer->From = SMTP_FROM;
$phpmailer->FromName = SMTP_NAME;
}
and wp-config.php
// SMTP email settings
define( \'SMTP_USER\', \'{email}\' );
define( \'SMTP_PASS\', \'{password}\' );
define( \'SMTP_HOST\', \'{server}\' );
define( \'SMTP_FROM\', \'{from}\' );
define( \'SMTP_NAME\', \'{name}\' );
define( \'SMTP_PORT\', \'465\' );
define( \'SMTP_SECURE\', \'ssl\' );
define( \'SMTP_AUTH\', true );
"wp-login.php?action=lostpassword" when I go here, I enter my e-mail address and click the send button,
"Failed to send e-mail. Your site may not be properly configured to send e-mail." I am getting this error.
But when I paste the same code into another WordPress with WooCommerce plugin installed,
I forgot my WooCommerce password. Mail can be successfully sent from the front-end design.
Where is the problem? Am I doing something wrong?
3rd step
add_action( \'wp_mail_failed\', function ( $error ) {
error_log( $error->get_error_message() );
} );
Not working (IDK). But I searched and found the code below,
add_action(\'wp_mail_failed\', \'log_mailer_errors\', 10, 1);
function log_mailer_errors( $wp_error ){
$fn = ABSPATH . \'/mail.log\'; // say you\'ve got a mail.log file in your server root
$fp = fopen($fn, \'a\');
fputs($fp, "Mailer Error: " . $wp_error->get_error_message() ."\\n");
fclose($fp);
}
This gave me the following error
Mailer Error: Invalid address: (From): wordpress@localhost
I found the relevant location from pluggable.php.
Since I was working on localhost, it was emitting an invalid e-mail address because it did not create a valid TLD.
if ( ! isset( $from_email ) ) {
// Get the site domain and get rid of www.
$sitename = wp_parse_url( network_home_url(), PHP_URL_HOST );
if ( \'www.\' === substr( $sitename, 0, 4 ) ) {
$sitename = substr( $sitename, 4 );
}
$from_email = \'wordpress@\' . $sitename;
}
This means, "$phpmailer->From = SMTP_FROM;" instead of "add_filter (\'wp_mail_from\', \'set_from\');" should use.
function set_from()
{
return \'[email protected]\';
}
add_filter(\'wp_mail_from\', \'set_from\');
Works now.
I don\'t understand why phpmailer_init doesn\'t overwrite from information.
By the way, the sender still appears to be what I defined in ($phpmailer-> From).
I guess this is some kind of bug and should be reported to WordPress?

问题出在哪里？我做错什么了吗？
您的代码对我来说似乎很好，因此尽管我无法给出问题的确切答案，但我认为这些可能有助于您解决问题：
首先，检查您的配置-例如，您是否使用了正确的（SMTP）用户名/电子邮件、密码、主机？
并确保SMTP_FROM 值是有效的email addresss — e、 g。[email protected] 而不是user@example 或User <[email protected]>; 否则，将不会发送电子邮件。
如果您确定配置良好，那么由于您使用SMTP，请尝试启用类似的调试-将此添加到my_phpmailer_example() 功能：
// Note: I assumed you\'re using at least WordPress version 5.5.0
$phpmailer->SMTPDebug = PHPMailer\\PHPMailer\\SMTP::DEBUG_SERVER;
然后访问WordPress的密码重置页面并尝试重置密码，在下一页，如果PHPMailer无法发送电子邮件，则会在页面顶部显示错误消息。
如果无法执行上述SMTP调试（实际上这只是一个快速故障排除），请启用debugging in WordPress 并使用wp_mail_failed hook 要尝试捕获发送电子邮件时的任何错误，请将其添加到函数文件中：
add_action( \'wp_mail_failed\', function ( $error ) {
error_log( $error->get_error_message() );
} );
然后检查
wp-content/debug.log 归档并查看是否有任何相关错误/信息。
更新（抱歉，我忍不住要说这句话）我喜欢这个问题，很高兴你解决了这个问题
I guess this is some kind of bug and should be reported to WordPress?
也许吧，但如果他们能做些什么来避免问题的发生，这绝对是一件好事，特别是因为有很多人在
localhost.
但万一你不知道，你可以使用虚拟主机，比如localhost.dev 这样就可以避免这个问题。
由于我使用的是localhost，它发出的电子邮件地址无效，因为它没有创建有效的TLD。
是的，我猜你已经在wp_mail() 代码（inpluggable.php):
/*
* If we don\'t have an email from the input headers, default to wordpress@$sitename
* Some hosts will block outgoing mail from this address if it doesn\'t exist,
* but there\'s no easy alternative. Defaulting to admin_email might appear to be
* another option, but some hosts may refuse to relay mail from an unknown domain.
* See https://core.trac.wordpress.org/ticket/5007.
*/
所以是的，要么使用
wp_mail_from hook 或者正如我上面所说的，使用虚拟主机。
我不明白为什么phpmailer_init 不覆盖from信息
因为WordPress/wp_mail() calls $phpmailer->setFrom() 设置From 属性，如果PHPMailer引发异常/错误（例如，由于电子邮件地址无效），则wp_mail() 退货false 永远不要点燃phpmailer_init 挂钩。
但是wp_mail_failed hook确实会被解雇，因此它是一种很好的方法，可以捕获使用wp_mail(). <（对不起，我没提过earlier 因为我认为SMTP调试也适用于您：））
By the way, the sender still appears to be what I defined in ($phpmailer->From).
是的，这很正常，因为
setFrom() 在
phpmailer_init 吊钩已启动。
事实上，当我说；在WordPress中启用调试；，我的意思是WP_DEBUG 和WP_DEBUG_LOG 常量到true; 如果error_log() 不写信给wp-content/debug.log （或通过WP_DEBUG_LOG 常数），则可以使用第2个和第3个参数error_log() 像这样：
add_action( \'wp_mail_failed\', function ( $error ) {
// the "3" means write the message to the file as defined in the third parameter
error_log( $error->get_error_message(), 3, WP_CONTENT_DIR . \'/debug.log\' );
} );
但无论如何，我希望这个答案/更新和这个问题也能帮助其他人。=）快乐的编码！
