本地主机上的 Laravel - 无法与主机 smtp.gmail.com 建立连接 [连接超时 #110]

我正在尝试使用 Mailgun

'driver' => env('MAIL_DRIVER', 'mailgun'),
'host' => env('MAIL_HOST', 'smtp.mailgun.org'),
'port' => env('MAIL_PORT', 587),


MAILGUN_DOMAIN=xxxxxxxxxx,
MAILGUN_SECRET=xxxxxxxxxx,

MAIL_DRIVER=smtp



MAIL_HOST=smtp.mailtrap.io
MAIL_PORT=2525
MAIL_USERNAME=null
MAIL_PASSWORD=null
MAIL_ENCRYPTION=null

这个错误很奇怪。为什么它会尝试连接到 Gmail？

Connection could not be established with host smtp.gmail.com [Connection timed out #110]

Edit:

Now I am getting

"mail" => array:9 [▼
      "driver" => "smtp"
      "host" => "smtp.mailgun.org"
      "port" => "2525"
      "from" => array:2 [▶]
      "encryption" => null
      "username" => null
      "password" => null
      "sendmail" => "/usr/sbin/sendmail -bs"
      "markdown" => array:2 [▼
        "theme" => "default"

My 邮件主机 was mailtrap.io，并且该 URL 似乎不再有效。

当我把它改成smtp.mailtrap.io它又开始工作了。
