windows dns 設定 Mx A records

PASS

Differing MX-A records

OK. I did not detect differing IPs for your MX records (this would happen if your DNS servers return different IPs than the DNS servers that are authoritative for the hostname in your MX records).

PASS

Duplicate MX records

OK. You do not have any duplicate MX records (pointing to the same IP). Although technically valid, duplicate MX records can cause a lot of confusion, and waste resources.

FAIL

Reverse DNS entries for MX records

ERROR: None of your mail server(s) seem to have reverse DNS (PTR) entries (I didn't get any responses for them). 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 (it contacts your servers in real time; the reverse DNS lookups in the DNS report use our local caching DNS server).

FAIL

Connect to mail servers

ERROR: I could not complete a connection to any of your mailservers!

59.120.10.166: Could not connect without glue or A record.<br />

If this is a timeout problem, note that the DNSreport only waits about 40 seconds for responses, so your mail *may* work fine in this case but you will need to use testing tools specifically designed for such situations to be certain.

誰可幫我 看看 這紅色部分 問題出在哪 我是win 2000 server

已更新項目:

ERROR: One or more of your nameservers reports that it is an open DNS server.

非常感謝你的回答 想請教 你回答的最後的open DNS server 不宜把 recursive 查詢服務完全開放, 那我在win2000server 上該怎嚜設定呢

    這是 dnsreport 的線上檢查結果,

    * Reverse DNS entries for MX records

    你的 MX record (負責該網域的收信主機,也可能是擋在前面做過濾的)

    所用的IP並沒有定義反解PTR record .

    假設MX主機IP是 11.22.33.44 ,

    就應該要有 44.33.22.11.in-addr.arpa 的反解 PTR record

    * 無法連上任何的 mail server

    找不到任何關於 mail server 的 A record.

    可能沒有給 mail server 定義 IP (A record),

    或者網域上層跟你這層的授權沒有做好,

    也有可能是其它因素(斷線,路由器,防火牆)以致於

    dnsreport無法連上你的mail server.

    不過我測試了一下你的網域(是 h*****.com.tw 對嗎?)

    看起來應該是不會有上述的情況才對.

    TWNIC也有提供線上簡測

    http://rs.twnic.net.tw/cgi-bin/dns.cgi

    * open DNS server ( 不是OpenDNS喔 )

    是說你的 name server 是任何人都可以拿來查任何網域的,

    因安全上的理由, 負責授權回應的DNS(Authoritative DNS )

    不宜把 recursive 查詢服務完全開放,

    只給自家人可以 recursive 查詢就好.

    很抱歉我只用過BIND架在Linux/FreeBSD/Solaris等平台上,

    就是沒用過Windows的DNS, 找了好久, 這份文件可能是最接近你想要的.

    記得設定完一定要仔細測試.
