554 Relay access denied 尝试从Outlook客户端发送电子邮件时出现此错误.

我可以阅读收到的邮件,但无法发送.

如果我连接telnet localhost 25我可以发送外部电子邮件,但与Outlook客户端它不起作用.

这是我的postfix和dovecot配置:

postconf -n

alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
append_dot_mydomain = no
biff = no
config_directory = /etc/postfix
inet_interfaces = all
mailbox_size_limit = 0
mydestination = localhost
myhostname = mail.mydomain.com
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
myorigin = /etc/mailname
readme_directory = no
recipient_delimiter = +
relayhost =
smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
smtpd_recipient_restrictions = permit_sasl_authenticated, permit_mynetworks, reject_unauth_destination
smtpd_sasl_auth_enable = yes
smtpd_sasl_path = private/auth
smtpd_sasl_type = dovecot
smtpd_tls_auth_only = yes
smtpd_tls_cert_file = …

我刚刚在生产服务器上上传了我的网站,我收到错误:

Warning: mysql_real_escape_string(): Access denied for user 'www-data'@'localhost' (using password: NO) in file.php on line 106

Warning: mysql_real_escape_string(): A link to the server could not be established in file.php on line 106

函数的代码是

include('./../inc/conn.php');
if(isset($_GET['query']))$q = clean($_GET['query']);
function clean($var){
    return(mysql_real_escape_string($var));
}   

inc/conn.php的代码:

try {
  $dns = 'mysql:host=localhost;dbname=mydatabase';
  $user = 'root';
  $pw = 'rootpw';

  $options = array(
    PDO::MYSQL_ATTR_INIT_COMMAND    => "SET NAMES utf8",
    PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION
  );

  $db = new PDO( $dns, $user, $pw, $options );
} catch ( Exception $e ) …
