救人喔！被退信，DNSReport說連接不到mailserver

[su14]

各位前輩，這幾天剛架好MailD和DNSD
收發mail正常，但也時常被退信，
退信訊息為451 4.1.8 Domain of sender address XXX@pusamam.com does not resolve

於是去Dnsreport測Connect to mail servers，還真的顯示失敗
ERROR: I could not complete a connection to one or more of your mailservers:
dns.pusamam.com: Could not connect without glue or A record.
dns.pusamam.com: Could not connect without glue or A record.
dns.pusamam.com: Could not connect without glue or A record.

可是用telnet測25 port又可正常連線，沒掛阿
真是奇怪，請問各位有何麼建議呢

以下是dns的設定
$ORIGIN pusamam.com.
@ IN SOA dns.pusamam.com. postmaster.pusamam.com. 2006070409 7200 3600 1800000 7200
@ IN A 220.130.85.88
@ IN NS dns.pusamam.com.
@ IN NS mail.pusamam.com.
@ IN MX 10 dns.pusamam.com.
www.pusamam.com. IN A 220.130.85.88
ftp.pusamam.com. IN A 220.130.85.88
dns.pusamam.com. IN A 220.130.85.88
dns.pusamam.com. IN MX 10 dns.pusamam.com.
mail.pusamam.com. IN A 220.130.85.88

系統條件：
用的都是最新版的 DNSD, MailD 以及ftpd ，系統為win2000server版
在3com office的Router下面使用虛擬server功能對應port 25, 110, 53, 21

dns.pusamam.com. IN MX 10 dns.pusamam.com.
這一行要改成
pusamam.com. IN MX 10 dns.pusamam.com.

謝謝各位的幫忙!

小弟已解決了！

梨子大哥說得那行上面已經有了@ IN MX 10 dns.pusamam.com.
因為還是有問題所以又增了dns.pusamam.com IN MX 10 dns.pusamam.com.
當然還是有問題，最後死心只好換了內建的DNS service，dnsreport 才正常

再次謝謝各位
