我目前租用 IP 1.1.1.1 的专用服务器，并添加了一个 IP 为 1.1.1.2 的域，DNS 记录 (domain.com/mail.domain.com)、MX 记录、SPF 记录等都指向 1.1。 1.2

问题是当我从该域的标题中发送电子邮件时，它显示服务器的主机名和 IP (1.1.1.1) 而不是其专用 IP。是否可以只显示其专用 IP 和域的主机名？

我在 Ubuntu 14.04 上使用 Postfix 和 Dovecot

谢谢！

我有以下 DNS 记录，我想问一下删除不需要的条目是否可以/安全：admin/ftp/m/mail/webmail（我希望邮件不会影响电子邮件？）

@   IN  NS  ns0.domainname.com.
@   IN  NS  ns1.domainname.com.
@   IN  NS  ns2.domainname.com.
ns0.domainname.com. IN  A   xx.xxx.xxx.xx
ns0.domainname.com. IN  AAAA    xxxx:xxxx:x::x
ns1.domainname.com. IN  A   xx.xxx.xxx.xx
ns1.domainname.com. IN  AAAA    xxxx:xxxx:x::x
ns2.domainname.com. IN  A   xx.xxx.xxx.xx
ns2.domainname.com. IN  AAAA    xxxx:xxxx:x::x
@       IN  A   xx.xxx.xxx.xx
@       IN  MX  5 mail.domainname.com.
@       IN  TXT "v=spf1 a mx aip4:xx.xxx.xxx.xx ?all"
admin   IN  A   xx.xxx.xxx.xx
ftp     IN  A   xx.xxx.xxx.xx
m       IN  A   xx.xxx.xxx.xx
mail    IN  A   xx.xxx.xxx.xx
webmail IN  A   xx.xxx.xxx.xx
www     IN  A   xx.xxx.xxx.xx

由于这些子域中的大多数最终都出现在 apache 安装页面中。

我正在尝试创建一个安装 MariaDB 的配置文件，但它一直失败。

该规定如下所示：

sudo apt-get install -y software-properties-common
sudo apt-key adv --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 0xcbcb082a1bb943db
sudo add-apt-repository 'deb http://ftp.cc.uoc.gr/mirrors/mariadb/repo/10.0/ubuntu trusty main'

apt-get update -y
apt-get install -y mariadb-server

我得到的错误是：

似乎无法打开要求您输入密码的终端并失败。我总是可以手动安装 MariaDB，但我想通过配置文件来安装。有什么想法/建议吗？
