PHP mail函数不适用于Postfix RHEL8

编程问答 2022-06-06

问题描述

有人可以帮助我吗？我已经将这个问题困扰了将近一个星期。我试图找到一种解决方案，但到目前为止没有用。

我不知道/不知道我在这里缺少什么。我查看了许多帖子和解决方案，并进行了尝试，但似乎没有任何帮助。

我已经在RHEL 8中安装了 Postfix / Dovecot 。我删除了sendmail。我只使用postfix和dovecot。

我正在关注本教程。但是到目前为止还没什么工作。

我的目标是使用 PHP mail（）函数发送电子邮件。

PHP代码显示成功，但是收件箱中没有收到任何电子邮件

这是我的email.PHP，位于 /var/www/html/email.PHP 

<?PHP 
error_reporting(-1);
ini_set('display_errors','On');
set_error_handler("var_dump");


$header = "From: nor[email protected]\r\n";
$header.= "MIME-Version: 1.0\r\n";
$header.= "Content-Type: text/html; charset=ISO-8859-1\r\n";
$header.= "X-Priority: 1\r\n";

$to      = "[email protected]";
$subject = "Test email from RHEL8";
$message = "test content"; 

$status = mail($to,$subject,$message,$header);

if($status)
{
    echo '<p>Your mail has been sent!</p>';
} else {
    echo '<p>Something went wrong. Please try again!</p>';
}
?>

这是我在/ var / log / maillog中的邮件日志。如下错误

这是我的/etc/postfix/main.cf 

compatibility_level = 2
queue_directory = /var/spool/postfix
command_directory = /usr/sbin
daemon_directory = /usr/libexec/postfix
data_directory = /var/lib/postfix

smtpd_tls_security_level = may
smtp_tls_CApath = /etc/pki/tls/certs
smtp_tls_CAfile = /etc/pki/tls/certs/ca-bundle.crt

smtp_tls_security_level = may
Meta_directory = /etc/postfix
shlib_directory = /usr/lib64/postfix

对于Dovecot /etc/dovecot/dovecot.conf，我如下更改文件。

listen = *
dict {
  #quota = MysqL:/etc/dovecot/dovecot-dict-sql.conf.ext
  #expire = sqlite:/etc/dovecot/dovecot-dict-sql.conf.ext
}
!include conf.d/*.conf
!include_try local.conf

对于/etc/dovecot/conf.d/10-auth.conf文件，我添加了这两行。

disable_plaintext_auth = no
auth_mechanisms = plain login

对于/etc/dovecot/conf.d/10-mail.conf文件，我仅编辑此行

mail_location=maildir:~/Maildir

对于/etc/dovecot/conf.d/10-master.conf文件，我编辑此行

unix_listener /var/spool/postfix/private/auth {
                  mode = 0666
                  user = postifx
                  group = postfix
             }

对于/etc/dovecot/conf.d/10-ssl.conf，我仅编辑此行

ssl = yes

然后，我重新启动服务器，重新启动postfix并运行

systemctl enable --Now dovecot
firewall-cmd --add-service=pop3 --permanent
firewall-cmd --add-service=imap --permanent
firewall-cmd --reload

但是我的邮件日志中仍然出现错误。有人真的可以帮我解决这个问题吗？我被困了将近一个星期。我仍然无法使用简单的PHP mail（）发送电子邮件。

帮助。非常感谢。
