1.刚才看了下是这样mx记录
> set q=mx
> nsitp.com
Server: tempdns.guangzhou.gd.cn
Address: 61.144.56.100
DNS request timed out.
timeout was 2 seconds.
nsitp.com
primary name server = ns.dns.net.cn
responsible mail addr = admin.nsn.idc
serial = 119
refresh = 900 (15 mins)
retry = 600 (10 mins)
expire = 86400 (1 day)
default TTL = 3600 (1 hour)
2。但是使用foxmail的特快专递,可以找到他们服务器,(我乱写了一个他们的地址)也收到退信
Hi. This is the qmail-send program at nsitp.com.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.
<tst@nsitp.com>:
Sorry, no mailbox here by that name. vpopmail (#5.1.1)
3。这个退信的头是:
Return-path: <>
Received: from 203.88.192.133 ([61.144.53.205])
by xxx.com (xxx.com [xx.xxx.xx.xx])头是这样的:
为什么nslookup mx记录时候,出现那样的结果
却可以找到他们的mail server? |
