小弟的邮件服务器现在彻底只能收信不能发信了,Queuese中的所有的进程都在Retry。<br>
小弟用www.dnsreport.com侦测了下,发现MX有个fail:Reverse DNS entries for MX records<br>
具体内容如下:<br>
ERROR: The IP of one or more of your mail server(s) have no reverse DNS (PTR) entries (if you see "Timeout" below, it may mean that your DNS servers did not respond fast enough). RFC1912 2.1 says you should have a reverse DNS for all your mail servers. It is strongly urged that you have them, as many mailservers will not accept mail from mailservers with no reverse DNS entry. You can double-check using the 'Reverse DNS Lookup' tool at the DNSstuff site. The problem MX records are:<br>
XXX.XXX.XXX.XXX.in-addr.arpa [No reverse DNS entry (rcode: 3 ancount: 0)]<br>
如何解决阿!?<br>
谢谢了!· |
