为什么我的dovecot收不到别人发来的邮件？

为什么我的dovecot收不到别人发来的邮件？

postfix 和 dovecot 安装在我的 vps--centos7 上。

我可以给别人发邮件，为什么收不到别人发的邮件？

端口没有问题。

netstat -an
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address           Foreign Address         State      
tcp        0      0 0.0.0.0:110             0.0.0.0:*               LISTEN     
tcp        0      0 0.0.0.0:143             0.0.0.0:*               LISTEN     
tcp        0      0 0.0.0.0:25              0.0.0.0:*               LISTEN

远程登录我的 vps。

telnet xxxxxxx  110
Trying xxxxxxxx...
Connected to xxxxxx
Escape character is '^]'.
Connection closed by foreign host.

用 关闭防火墙是没有用的 systemctl stop firewalld。

如何检查我的鸽舍的错误？
1、doveconf -n

first_valid_uid = 1000

mbox_write_locks = fcntl

  mailbox Drafts {
    special_use = \Drafts
  }
  mailbox Junk {

  mailbox "Sent Messages" {

  mailbox Trash {
    special_use = \Trash
  }
  prefix =

passdb {
  driver = pam

service auth {

    group = postfix
    mode = 0660
    user = postfix
  }
  unix_listener auth-userdb {
    mode = 0600
    user = vmail
  }
}
ssl = required
userdb {
  driver = passwd
}

  2. 远程登录xxxx 25

    正在尝试 xxxx
    连接到 xxxxxx
    转义字符为“^]”。
    220 xxxxxx ESMTP 后缀

答案1

做

dig domain.tld in MX

给您一个回复，显示如下内容：

domain.tld.  86400 IN MX 10 mail.domain.tld.

如果没有，您需要在 DNS 中添加 MX 记录，如下所示：

owner-name           ttl  class   rr  pref name
example.com.         3w   IN      MX  10   mail.example.com.

这是一个不错的解释以及上面示例的来源：

zytrax.com 上的邮件交换记录 (MX)

答案2

dig  mydomain.com in MX

;; AUTHORITY SECTION:
mydomain.com        285 IN  SOA 


dig  mail.mydomain.com  in MX

;; ANSWER SECTION:
mail.mydomain.com.  300 IN  MX  10 mydomain.com

mydomain.com 未添加 MX 记录，mail.mydomain.com 添加了 MX 记录。

在 DNS 中为 mydomain.com 添加 MX 记录，而不是在我的域名服务器中添加 mail.mydomain.com。

owner-name           ttl  class   rr  pref name
mydomain.com         3w   IN      MX  10   mydomain.com
