Question

我正在尝试使用以下PHP代码发送电子邮件：

        require("PHPMailer-master/src/PHPMailer.php");
        require("PHPMailer-master/src/SMTP.php");
        require("PHPMailer-master/src/Exception.php");

        $from  = "admin@mydomain.com";
        $namefrom = "admin";
        $mail = new PHPMailer\PHPMailer\PHPMailer();
        $mail->isSMTP();   // by SMTP
        $mail->SMTPDebug = 1;
        $mail->SMTPAuth   = true;   // user and password
        $mail->Host       = "mail.gandi.net";
        $mail->Port       = 110;
        $mail->Username   = $from;
        $mail->Password   = "Password123";

        $mail->CharSet = 'UTF-8';
//        $mail->SMTPSecure = "";    // options: 'ssl', 'tls' , ''  
        $mail->setFrom($from,$namefrom);   // From (origin)
        $mail->addCC($from,$namefrom);      // There is also addBCC
        $mail->Subject  = "Some subject";
        $mail->AltBody  = "Altenrate";
        $mail->Body = "Heyheyhey";
        $mail->isHTML(false);   // Set HTML type
        $mail->addAddress("hello@hotmail.com", "hello@hotmail.com");
        if($mail->send())
        {
          echo "ok sent";
        }
        else
        {
             echo "Mailer Error: " . $mail->ErrorInfo;
        }

    }

使用此代码时，需要花一些时间才能加载，最终向我显示此错误：

2018-12-09 20:50:24 CLIENT -> SERVER: EHLO www.mydomain.be
2018-12-09 20:53:24 SMTP ERROR: EHLO command failed: -ERR Unknown command.-ERR Disconnected for inactivity.
2018-12-09 20:53:24 SMTP NOTICE: EOF caught while checking if connected
SMTP Error: Could not authenticate.
SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting
Mailer Error: SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting

有人可以向我解释这个问题是什么以及如何解决它？

谢谢！

Answer 1

根据：https://docs.gandi.net/en/gandimail/standard_email_settings/index.html

您的设置有误

应该是

Outgoing (SMTP) server name: mail.gandi.net
Port: 25, 465 (with SSL) or 587 (with STARTTLS)
TLS or SSL: yes
SMTP Authentication: yes, using the same settings as for the POP / IMAP account

Answer 2

Hello traducerad，

(x 25)

端口110用于传入POP通信。
我认为您想通过SMTP发送电子邮件。

发送（SMTP）服务器名称：mail.gandi.net
  端口：25、465（使用SSL）或587（使用STARTTLS）
  TLS或SSL：是
  SMTP身份验证：是，使用与POP / IMAP帐户相同的设置
