被YAHOO退信

各位大大,
我補充一下我們公司是用2個512/512 ADSL,一家是HI-NET,一家是SeedNET

我到DNSREPORT查DNS MX都正常,但是找不到MailServer,

Mail FAIL Connect to mail servers ERROR: I could not complete a connection to any of your mailservers!

mail2.ck2.com.tw: Could not receive data: Winsock error #10053 (state

.
mail.ck2.com.tw: Connection closed before I received all my data (state

. Your mailserver disconnected before it was done! This may be the result of a non-RFC-compliant mailserver or anti-spam program.

If this is a timeout problem, note that the DNS report only waits about 30 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.

後來對[HINET]Reverse DNS for 61.221.165.74

Country: TAIWAN

Preparation:
The reverse DNS entry for an IP is found by reversing the IP, adding it to "in-addr.arpa", and looking up the PTR record.
So, the reverse DNS entry for 61.221.165.74 is found by looking up the PTR record for
74.165.221.61.in-addr.arpa.
All DNS requests start by asking the root servers, and they let us know what to do next.
See How Reverse DNS Lookups Work for more information.

How I am searching:
Asking c.root-servers.net for 74.165.221.61.in-addr.arpa PTR record:
c.root-servers.net says to go to ns3.apnic.net. (zone: 61.in-addr.arpa.)
Asking ns3.apnic.net. for 74.165.221.61.in-addr.arpa PTR record:
ns3.apnic.net [202.12.28.131] says to go to rns2.twnic.net. (zone: 221.61.in-addr.arpa.)
Asking rns2.twnic.net. for 74.165.221.61.in-addr.arpa PTR record:
rns2.twnic.net [61.220.48.10] says to go to ipdns2.hinet.net. (zone: 165.221.61.in-addr.arpa.)
Asking ipdns2.hinet.net. for 74.165.221.61.in-addr.arpa PTR record: Reports 61-221-165-74.HINET-IP.hinet.net. [from 168.95.1.14]

Answer:
61.221.165.74 PTR record: 61-221-165-74.HINET-IP.hinet.net. [TTL 86400s] [A=61.221.165.74]

也對[SEEDNET]Reverse DNS for 203.70.28.65

Country: TAIWAN

Preparation:
The reverse DNS entry for an IP is found by reversing the IP, adding it to "in-addr.arpa", and looking up the PTR record.
So, the reverse DNS entry for 203.70.28.65 is found by looking up the PTR record for
65.28.70.203.in-addr.arpa.
All DNS requests start by asking the root servers, and they let us know what to do next.
See How Reverse DNS Lookups Work for more information.

How I am searching:
Asking b.root-servers.net for 65.28.70.203.in-addr.arpa PTR record:
b.root-servers.net says to go to ns.ripe.net. (zone: 203.in-addr.arpa.)
Asking ns.ripe.net. for 65.28.70.203.in-addr.arpa PTR record:
ns.ripe.net [193.0.0.193] says to go to ksdns.seed.net.tw. (zone: 70.203.in-addr.arpa.)
Asking ksdns.seed.net.tw. for 65.28.70.203.in-addr.arpa PTR record: Reports h65-203-70-28.seed.net.tw. [from 139.175.10.20]

Answer:
203.70.28.65 PTR record: h65-203-70-28.seed.net.tw. [TTL 86400s] [A=None] *ERROR* A record does not point back to original IP.

這兩個結果不太一樣,看起來SEEDNET是不是有問題?

謝謝！

你用什麼網路設備跟申請反解無關.

所謂ADSL, 就是撥號的網路, 走的是PPPOE協定.
既是撥號, 當然是ISP機房指派 IP 給你的ADSL modem 對應端(位於機房),
而這個給你用的 IP, 預設都是以ISP 機房的網域的預設名稱
為你 IP 的反解名稱(當然他不知道你要用的網路反解該設成什麼公司網域, 什麼用途...), 所以你才要跟他申請(因為你有郵件的用途), 指派這個 IP 的反解名稱為你的公司網域下的一個名稱.(ADSL 的 IP 都是ISP的, 只是他給你用而已)
