防止PHP郵件發送到垃圾郵件gmail

這是我用來從網站上的聯繫表單發送電子郵件的完整代碼。儘管所有的最佳實踐使用（標題等），結果是：防止PHP郵件發送到垃圾郵件gmail

1）確認電子郵件給用戶去在每次Gmail的垃圾郵件，它是已檢舉爲詐騙

2）管理員的電子郵件被標記作爲網絡釣魚

有人可以幫我嗎？謝謝！

嘗試使用swiftmailer發送它，我敢打賭問題消失。 – mkaatman

您無法明確地控制您的電子郵件是否被標記爲垃圾郵件，但有些事情可以幫助您做。

確保您的反向DNS是正確的。
執行SPF。
執行DKIM。
本地安裝SpamAssassin並通過詳細模式運行您的消息樣本，以瞭解它們爲什麼會被標記。
使用類似MailChimp或MailGun的服務而不是本地交付方。

您需要使用標題。這爲我工作：

$to = "[email protected]"; 
$subject = "your subject"; 
$body = "<p>Your Body</p>"; 
$headers = "From: Sender Name <[email protected]>" . "\r\n"; 
$headers .= 'MIME-Version: 1.0' . "\r\n"; 
$headers .= "Content-type: text/html; charset=iso-8859-1\r\n"; 
mail($to, $subject, $body, $headers);

此外，您可以在您的註冊添加TXT Record爲SPF，你有你的域名。進入DNS設置，並添加以下TXT記錄：

類型：TXT
主持人：example.com
值：v=spf1 ip4:YOUR.SERVER.IP.HERE ~all
TTL：Automatic

這是用來驗證該郵件沒有被欺騙。

我已經在使用標題。現在我將嘗試在域中設置註冊。謝謝 –
