为什么从 phpmailer 发送时发件人会被 postfix 拒绝？

Question

当我运行以下 PHP 代码时，出现错误。

$mail = new PHPMailer;

$mail->isSMTP();

$mail->SMTPDebug = SMTP::DEBUG_SERVER; // debug

$mail->Host = 'localhost';

$mail->Port = 25;

$mail->SMTPAuth = true;

$mail->Username = $uname;

$mail->Password = $pw;

$mail->CharSet = PHPMailer::CHARSET_UTF8;

$mail->setFrom('[e-mail]', 'website registration');

$mail->addAddress($cleaned_email);

$mail->Subject = 'Please verify your account';

$msg = '[registration text...]'

$msg = wordwrap($msg, 70);

$mail->Body = $msg;

                        

if (!$mail->send()) {

  echo $mail->ErrorInfo;

  exit();

} else {

  [... add user to db, etc...]

}

邮件似乎已发送。PHPMailer 不会生成任何错误，并且数据库代码会运行。

这是在 mail.log 中生成的错误。

Aug 22 11:47:06 server postfix/smtp[8339]: 079AB1F909: to=<outsider-at-anydomain.com>, relay=mail.brighthouse.com[47.43.26.56]:25, delay=5.7, delays=0.06/0.02/0.31/5.3, dsn=2.0.0, status=sent (250 2.0.0 <user-at-example.com> sender rejected. Please see understanding-email-error-codes for more information.)

我尝试将发送地址更改为我在 PHP 代码中进行身份验证的用户。

我尝试将带有匹配哈希表的 smtpd_sender_login_maps 参数添加到我的后缀配置中，以将无回复地址映射到我进行身份验证的用户，但它会将其作为未使用的参数忽略。

后缀配置：

# See /usr/share/postfix/main.cf.dist for a commented, more complete version

# Debian specific:  Specifying a file name will cause the first

# line of that file to be used as the name.  The Debian default

# is /etc/mailname.

#myorigin = /etc/mailname

smtpd_banner = $myhostname ESMTP $mail_name (Raspbian)

biff = no

# appending .domain is the MUA's job.

append_dot_mydomain = no

# Uncomment the next line to generate "delayed mail" warnings

#delay_warning_time = 4h

readme_directory = no

# See http://www.postfix.org/COMPATIBILITY_README.html -- default to 2 on

# fresh installs.

compatibility_level = 2

Answer 1

“发件人”地址的语法不正确：$mail->setFrom('在示例 .com 处无回复', '网站注册');您需要使用有效的电子邮件地址，例如：$mail->setFrom('[e-mail]',&nbsp;'website&nbsp;registration');

Answer 2

我的问题与 PHP Mailer 无关。我发布的 php 代码有效。我的问题是我的电子邮件服务器设置。
