Dockerfile

我正在尝试的东西如下：-

docker exec -it GKapp bash

cat /usr/local/etc/php/php.ini
sendmail_path = /usr/bin/mhsendmail --smtp-addr mailhog:1025

/usr/bin/mhsendmail --help
Usage of /usr/bin/mhsendmail:
  -f, --from string        SMTP sender (default "www@2693eda79e6e")
  -i, --long-i             Ignored. This flag exists for sendmail compatibility. (default true)
  -o, --long-o             Ignored. This flag exists for sendmail compatibility. (default true)
  -t, --long-t             Ignored. This flag exists for sendmail compatibility. (default true)
      --smtp-addr string   SMTP server address (default "localhost:1025")
  -v, --verbose            Verbose mode (sends debug output to stderr)

/usr/bin/mhsendmail [email protected] <<EOF

Subject: Hello, Andy!

Hey there,
Missing you pig time.

Hogs & Kisses,

error sending mail
2022/08/31 12:52:42 dial tcp 127.0.0.1:1025: getsockopt: connection refused

因此，我无法使用 mailhog 从容器内以及本地文件系统上的脚本发送电子邮件：-

电子邮件.php

<?php

$to = "[email protected]";
$subject = "Hey, I’m Pi Hog Pi!";
$body = "Hello, MailHog!";
$headers = "From: [email protected]" . "\r\n";
mail($to, $subject, $body, $headers);

echo 'email sent';

以上方法都不管用吗？帮助。

我也遇到同样的问题。 通过这种方式安装即可解决问题：

RUN curl -LkSso /usr/bin/mhsendmail 'https://github.com/mailhog/mhsendmail/releases/download/v0.2.0/mhsendmail_linux_amd64'&&
chmod 0755 /usr/bin/mhsendmail &&
echo 'sendmail_path = "/usr/bin/mhsendmail --smtp-addr=mailhog:1025"' > /usr/local/etc/php/php.ini;
