This problem can generally occur when you do not enable two step verification for the gmailaccount (which can be done here) you are using to send an email. So first, enable two step verification, you can find plenty of resources for enabling two step verification. After you enable it, then you have to create an app password. And use the app passwordin your .envfile. When you are done with it, your .envfile will look something like.

当你不启用两步验证通常会出现此问题gmail的帐户（这是可以做到在这里使用的是发送）email。所以首先，启用two step verification，您可以找到大量资源来启用两步验证。启用它后，您必须创建一个app password. 并app password在您的.env文件中使用。完成后，您的.env文件将看起来像。

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
MAIL_USERNAME=<<your email address>>
MAIL_PASSWORD=<<app password>>
MAIL_ENCRYPTION=tls

and your mail.php

和你的 mail.php

<?php

return [
    'driver' => env('MAIL_DRIVER', 'smtp'),
    'host' => env('MAIL_HOST', 'smtp.gmail.com'),
    'port' => env('MAIL_PORT', 587),
    'from' => ['address' => '<<your email>>', 'name' => '<<any name>>'],
    'encryption' => env('MAIL_ENCRYPTION', 'tls'),
    'username' => env('MAIL_USERNAME'),
    'password' => env('MAIL_PASSWORD'),
    'sendmail' => '/usr/sbin/sendmail -bs',
    'pretend' => false,

];

After doing so, run php artisan config:cacheand php artisan config:clear, then check, email should work.

这样做之后，运行php artisan config:cache和php artisan config:clear，然后检查，电子邮件应该可以工作。

In my case I had to set the

在我的情况下，我必须设置

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=465           <<<<<<<------------------------- (FOCUS THIS)
MAIL_USERNAME=<<your email address>>
MAIL_PASSWORD=<<app password>>

MAIL_ENCRYPTION= ssl    <<<<<<<------------------------- (FOCUS THIS)

to work it.. Might be useful. Rest of the code was same as @Sid said.

工作它.. 可能有用。其余代码与@Sid 所说的相同。

And I think that editing both environment file and app/config/mail.php is unnecessary. Just use one method.

而且我认为编辑环境文件和 app/config/mail.php 是不必要的。只需使用一种方法。

Edit as per the comment by @Zan

根据@Zan 的评论进行编辑

If you need to enable tlsprotection use following settings.

如果您需要启用tls保护，请使用以下设置。

MAIL_PORT=587
MAIL_ENCRYPTION= tls

if you are using Swift Mailer: please ensure that your $transport variable is similar to the below, based on tests i have done, that error results from ssl and port misconfiguration. note: you must include 'ssl' or 'tls' in the transport variable.

如果您使用的是 Swift Mailer：请确保您的 $transport 变量与以下类似，根据我所做的测试，该错误是由 ssl 和端口配置错误导致的。 注意：您必须在传输变量中包含“ssl”或“tls”。

EXAMPLE CODE:

示例代码：

// Create the Transport
$transport = (new Swift_SmtpTransport('smtp.gmail.com', 465, 'ssl'))
  ->setUsername([email protected])
  ->setPassword(password)
;

// Create the Mailer using your created Transport
$mailer = new Swift_Mailer($transport);

// Create a message
$message = (new Swift_Message('News Letter Subscription'))
  ->setFrom(['[email protected]' => 'A Name'])
  ->setTo(['[email protected]' => 'A Name'])
  ->setBody('your message body')
  ;

// Send the message
$result = $mailer->send($message);

For me the problem was the port. I first incorrectly used port 465, which works for SSLbut not TLS. So the key thing was changing the port to 587.

对我来说，问题是端口。我第一次使用不正确的端口465，其适用于SSL但不是TLS。所以关键是将端口更改为 587。

That error message means that there was not response OR the server could not be connected.

该错误消息意味着没有响应或无法连接服务器。

The following settings worked on my end:

以下设置对我有用：

'stream' => [
        'ssl' => [
            'allow_self_signed' => true,
            'verify_peer' => false,
            'verify_peer_name' => false,
        ],
    ]

Note that my SMTP settings are:

请注意，我的 SMTP 设置是：

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=465
MAIL_USERNAME=[full gmail address]
MAIL_PASSWORD=[App Password obtained after two step verification]
MAIL_ENCRYPTION=ssl

I did as per sid saying my env after updating is

我按照 sid 说我的 env 更新后是

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
MAIL_USERNAME=<mygmailaddress>
MAIL_PASSWORD=<gmailpassword>
MAIL_ENCRYPTION=tls

this did work without 2 step verification. with 2 step verification enabled it did not work for me.

这在没有两步验证的情况下确实有效。启用两步验证后，它对我不起作用。
