邮件未通过 Mailgun 发送 API Laravel 8

Question

我正在尝试从我的控制器通过 mailgun API 发送邮件，但是邮件没有到达 mailgun，而且我没有收到任何错误 messages/logs。

这是我的 .env:

MAIL_MAILER=mailgun
MAILGUN_DOMAIN=subdomain.domain.ca
MAILGUN_SECRET=xxxxxxxxxxxxxxxxxxxxxxxxxxx

这是我的 services.php:

<?php

return [

    /*
    |--------------------------------------------------------------------------
    | Third Party Services
    |--------------------------------------------------------------------------
    |
    | This file is for storing the credentials for third-party services such
    | as Mailgun, Postmark, AWS, and more. This file provides the de facto
    | location for this type of information, allowing packages to have
    | a conventional file to locate the various service credentials.
    |
    */

    'mailgun' => [
        'domain' => env('subdomain.domain.ca'),
        'secret' => env('xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'),
    ],

    'postmark' => [
        'token' => env('POSTMARK_TOKEN'),
    ],

    'ses' => [
        'key' => env('AWS_ACCESS_KEY_ID'),
        'secret' => env('AWS_SECRET_ACCESS_KEY'),
        'region' => env('AWS_DEFAULT_REGION', 'us-east-1'),
    ],

];

这是我的 mail.php:

<?php

return [

    /*
    |--------------------------------------------------------------------------
    | Default Mailer
    |--------------------------------------------------------------------------
    |
    | This option controls the default mailer that is used to send any email
    | messages sent by your application. Alternative mailers may be setup
    | and used as needed; however, this mailer will be used by default.
    |
    */

    'default' => env('MAIL_MAILER', 'mailgun'),

    /*

    |
    | Here you may configure all of the mailers used by your application plus
    | their respective settings. Several examples have been configured for

    | Supported: "smtp", "sendmail", "mailgun", "ses",
    |            "postmark", "log", "array"
    |
    */

    'mailers' => [
        'smtp' => [
            'transport' => 'smtp',
            'host' => env('MAIL_HOST', 'smtp.mailgun.org'),
            'port' => env('MAIL_PORT', 587),
            'encryption' => env('MAIL_ENCRYPTION', 'tls'),
            'username' => env('MAIL_USERNAME'),
            'password' => env('MAIL_PASSWORD'),
            'timeout' => null,
            'auth_mode' => null,
        ],

        'ses' => [
            'transport' => 'ses',
        ],

        'mailgun' => [
            'transport' => 'mailgun',
        ],

        'postmark' => [
            'transport' => 'postmark',
        ],

        'sendmail' => [
            'transport' => 'sendmail',
            'path' => '/usr/sbin/sendmail -bs',
        ],

        'log' => [
            'transport' => 'log',
            'channel' => env('MAIL_LOG_CHANNEL'),
        ],

        'array' => [
            'transport' => 'array',
        ],
    ],

    /*
    |--------------------------------------------------------------------------
    | Global "From" Address
    |--------------------------------------------------------------------------
    |
    | You may wish for all e-mails sent by your application to be sent from
    | the same address. Here, you may specify a name and address that is
    | used globally for all e-mails that are sent by your application.
    |
    */

    'from' => [
        'address' => env('MAIL_FROM_ADDRESS', 'info@domain.ca'),
        'name' => env('MAIL_FROM_NAME', 'From name'),
    ],

    /*

    |--------------------------------------------------------------------------
    |
    | If you are using Markdown-based email rendering, you may configure your
    | theme and component paths here, allowing you to customize the design
    | of the emails. Or, you may simply stick with the Laravel defaults!
    |
    */

    'markdown' => [
        'theme' => 'default',

        'paths' => [
            resource_path('views/vendor/mail'),
        ],
    ],

];

这就是我在控制器中发送邮件的方式：

Mail::send('emailtemplates.trackeremail', $data, function($message)use($data, $pdf) {
                $message->to($data["toaddress"])
                        ->cc($data["ccaddress"])
                        ->subject($data["title"])
                        ->attachData($pdf->output(), "PDFName.pdf");
            });

当我在本地环境中通过 SMTP 发送到 mailgun 时，这是有效的，但不幸的是，我仅限于不允许第 3 方 SMTP 的共享主机，我需要切换到 API 生产方法。我已经阅读了本网站（和其他网站）上的许多相关教程和问题，但没有解决我的问题。

我总是运行 php artisan config:clear 在任何类型的 .env 改变之后。

我还能做些什么来获得错误消息或进一步调试吗？任何帮助将不胜感激。

Answer 1

可能是端口、主机、加密和邮件来自：

保持这些在您的 .env:

MAIL_MAILER=mailgun
MAIL_HOST=smtp.mailgun.org
MAIL_PORT=2525
MAIL_USERNAME=null
MAIL_PASSWORD=null
MAIL_ENCRYPTION=null

在您的 .env 中输入这些：

MAIL_FROM_NAME=YourNameHere
MAIL_FROM_ADDRESS=enter@theemail.com
MAIL_FROM=enter@theemail.com
MAILGUN_DOMAIN=subdomain.domain.ca
MAILGUN_SECRET=xxxxxxxxxxxxxxxxxxxxxxxxxxx

更新 services.php 为：

    'mailgun' => [
        'domain'   => env('MAILGUN_DOMAIN'),
        'secret'   => env('MAILGUN_SECRET'),
        'endpoint' => env('MAILGUN_ENDPOINT', 'api.mailgun.net'),
    ],

更新 mail.php 添加：

'encryption' => env('MAIL_ENCRYPTION', 'tls'),
'port' => env('MAIL_PORT', 587),

Answer 2

在与 A2 Hosting 的技术支持人员讨论后发现，这对于他们的共享主机来说是不可能的，我被告知“Mailgun 仅支持标准 SMTP 端口，因此我们的共享服务器不支持它".
