大佬教程收集整理的这篇文章主要介绍了linux – 暂停交付：找不到主机或域名，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
> mailad.ad.vz – 第一个域中的后缀服务器
> mailsh – 带有postfix和两个网络适配器的网关
> mailinet.ad2.vz – 第二个域中的后缀服务器
Sep 4 08:51:01 mailsh postfix/error[9602]: CFA5E131A7: to=<test@mailinet2.ad.vz>,relay=none,delay=33,delays=32/0/0/0,dsn=4.4.3,status=deferred (delivery temporarily suspended: Host or domain name not found. Name service error for name=mailinet.ad.vz type=MX: Host not found,try again)"
每次当适配器打开时,我发送命令postqueue -f
为什么队列可以积累？

运输设置：
* smtp:mailinet.ad.vz vzavod.ru smtp:mailad.ad.vz
>禁用自发SMTP邮件传递(如果仅使用按需拨号Ip).
使用以下参数,除非您手动运行postqueue -f,否则postfix不会尝试发送电子邮件.将此参数放在main.cf中.更多信息,请参见here.
defer_transports = smtp # (Only for on-demand dialup IP hosts)
>禁用SMTP客户端DNS查找(仅限拨号LAN).
禁用Postfix SMTP和LMTP客户端中的DNS查找.禁用时,将使用getaddrinfo()系统库例程查找主机,该例程通常也会在/ etc / hosts中查找.因此,将mailad.ad.vz的条目放在/ etc / hosts上.例如
# echo "192.168.1.99 mailad.ad.vz" >> /etc/hosts
并在main.cf中添加此参数
disable_dns_lookups = yes #(Only for on-demand dialup IP hosts)
