posfix 不向其他服务器发送/接收邮件

服务器上安装了 Debian 7.8、Postfix 2.9.6、Dovecot 2.1.7。服务器不接收或向外部服务器发送邮件。在域内，一切正常。

配置文件：

/etc/hosname
    vps-***.kz

主机名不能更改，它是由主机托管公司设置的。

/etc/mailname
    mail.domain.kz

Posfix 配置文件：

/etc/postfix/main.cf

日志文件中没有写入任何内容，空文件 /var/log/mail.*。Syslog 日志文件也是空的。

可能哪里出错了？

需要进行 SMTP 身份验证才能成功将电子邮件发送给外部用户。将以下几行添加到您的 main.cf 中：smtpd_recipient_restrictions = smtpd_sasl_auth_enable = yes smtpd_sasl_path = smtpd
