linux – SendMail错误消息：553 5.1.8 …发件人地址域…不存在

当我试图从其他电子邮件服务器发送dmail时,我收到以下错误,

This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its

------ This is a copy of the message,including all the headers. ------

我在192.168.1.145中安装了sendmail服务器. .145的域名是inhmail.walkingtree.in

我在系统和路由器的防火墙中打开了端口25.

192.168.1.0/24中的邮件接收和发送与@ inhmail.walkingtree.in一起正常工作.

请帮助sendmail如何从外部电子邮件服务器接收邮件.

工作：

是的,谢谢,现在它正在运作.

问题是我无法ping walktree.in,由于本地DNS服务器设置.我删除了网络连接中的dbs服务器现在我能够从GMail和walkingtree.in获取邮件

当我使用DNS服务器时,我可以ping www.walkingtree.in但不能walktree.in.你可以帮助我能够ping walktree.in
