我在本地使用inhmail.walkingtree.in设置sendmail服务器

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
recipients. This is a permanent error. The following address(es) failed:

------ 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

解决方法:

你sendmail认为信封发件人的域名walkingtree.in不存在(没有MX,A,AAAA DNS记录).它拒绝接受带有此类信封发件人的邮件,因为无法发回(最终)退回邮件(有关电子邮件传递问题的报告).

您可以使用nslookup(或dig)来检查服务器是否看到DNS记录：

nslookup -type = mx walkingtree.in
    挖掘walktree.in MX

如果您使用SENDMAIL(而不是后缀),那么以root身份执行以下命令来查找问题：

echo "check_mail jd@walkingtree.in" | sendmail -d8.20 -bt

如果出现“Undefined ruleset check_mail”错误,请尝试：

echo "checkmail jd@walkingtree.in" | sendmail -d8.20 -bt

-d8.20开启对DNS查询的跟踪
checkmail – 相当于与FEATURE一起使用的check_mail(delay_checks)
