如何在Laravel中配置多个发件邮箱适配不同业务场景

1. 补充.env环境变量 #

在现有.env的MAIL配置后面新增两套SMTP参数：

# 销售账单邮箱配置
MAIL_SALES_DRIVER=smtp
MAIL_SALES_HOST=smtp.mailtrap.io
MAIL_SALES_PORT=2525
MAIL_SALES_USERNAME=xxxxxxxxx
MAIL_SALES_PASSWORD=xxxxxxxxxxxxx
MAIL_SALES_FROM_ADDRESS=sales@mywebsite.com
MAIL_SALES_FROM_NAME="Sales"
MAIL_SALES_ENCRYPTION=TLS

# 客服通知邮箱配置
MAIL_SUPPORT_DRIVER=smtp
MAIL_SUPPORT_HOST=smtp.mailtrap.io
MAIL_SUPPORT_PORT=2525
MAIL_SUPPORT_USERNAME=yyyyyyyyy
MAIL_SUPPORT_PASSWORD=yyyyyyyyyyyyy
MAIL_SUPPORT_FROM_ADDRESS=support@mywebsite.com
MAIL_SUPPORT_FROM_NAME="Support"
MAIL_SUPPORT_ENCRYPTION=TLS

2. 修改config/mail.php注册多邮箱配置 #

找到mailers数组，新增两个自定义邮箱驱动配置项：

'mailers' => [
    // 原有默认的smtp配置保留
    'smtp' => [
        'driver' => env('MAIL_DRIVER', '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,
    ],
    // 新增销售账单邮箱配置
    'sales' => [
        'driver' => env('MAIL_SALES_DRIVER', 'smtp'),
        'host' => env('MAIL_SALES_HOST'),
        'port' => env('MAIL_SALES_PORT'),
        'encryption' => env('MAIL_SALES_ENCRYPTION', 'tls'),
        'username' => env('MAIL_SALES_USERNAME'),
        'password' => env('MAIL_SALES_PASSWORD'),
        'from' => [
            'address' => env('MAIL_SALES_FROM_ADDRESS'),
            'name' => env('MAIL_SALES_FROM_NAME'),
        ],
        'timeout' => null,
    ],
    // 新增客服通知邮箱配置
    'support' => [
        'driver' => env('MAIL_SUPPORT_DRIVER', 'smtp'),
        'host' => env('MAIL_SUPPORT_HOST'),
        'port' => env('MAIL_SUPPORT_PORT'),
        'encryption' => env('MAIL_SUPPORT_ENCRYPTION', 'tls'),
        'username' => env('MAIL_SUPPORT_USERNAME'),
        'password' => env('MAIL_SUPPORT_PASSWORD'),
        'from' => [
            'address' => env('MAIL_SUPPORT_FROM_ADDRESS'),
            'name' => env('MAIL_SUPPORT_FROM_NAME'),
        ],
        'timeout' => null,
    ],
    // 其他原有配置保持不变
],

3. 业务场景按需调用对应邮箱配置 #

发送邮件时先用mailer()方法指定要使用的配置标识即可：

• 账单相关业务用sales配置：

\Mail::mailer('sales')->to($firmAdminEmail->admin_email)->send(new AdminLeadAccept($acceptLink));

• 通知类及其他业务用support配置：

\Mail::mailer('support')->to($user->email)->send(new OrderNotify($orderInfo));

注意事项 #

修改配置后如果开启了配置缓存，需要执行php artisan config:cache刷新配置生效。
