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

当我尝试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:

  mail1@inhmail.walkingtree.in
    SMTP error from remote mail server after MAIL FROM:<srinivasa.nallapati@walkingtree.in> SIZE=2548:
    host inhmail.walkingtree.in [122.175.35.121]:
    553 5.1.8 <srinivasa.nallapati@walkingtree.in>... Domain of sender address srinivasa.nallapati@walkingtree.in does not exist

------ 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

我也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 一起工作正常。

请帮忙how sendmail can receive mails from external email servers.

在职的：

是的，谢谢，现在它正在工作。

问题是由于本地 DNS 服务器设置，我无法 ping walktree.in。我在网络连接中删除了 dbs 服务器，现在我可以从 GMail 和 walktree.in 获取邮件

当我使用 dns 服务器时，我可以 ping www.walkingtree.in 但不能ping walkingtree.in。你能帮我ping一下walkingtree.in吗

您 sendmail 认为信封发件人的域 walktree.in 不存在（没有MX, A, AAAADNS 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) 检查服务器是否看到 DNS 记录：

nslookup -type=mx walkingtree.in
dig walkingtree.in MX

如果您使用 SENDMAIL（不是 postfix），则以 root 身份执行以下命令来定位问题：

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 打开跟踪 DNS 查询
checkmail - 相当于与 FEATURE(delay_checks) 一起使用的 check_mail
