postfix安裝后測試發送郵件結果總是connection refused
centos 5.5
postfix 2.3。用yum安裝的。關閉了selinux和防火牆。
伺服器的名字是mail.test2051.com
MX記錄執向了A記錄
# dig test2051.com mx +short
10 mail.test2051.com.
# ping mail.test2051.com
PING mail.test2051.com (10.0.101.232) 56(84) bytes of data.
64 bytes from test2051.com (10.0.101.232): icmp_seq=1 ttl=64 time=0.027 ms
正是郵件伺服器自己。說明dns設置是正確的。
postfix已經啟動
# /etc/init.d/postfix status
master (pid 2388) is running...
使用下面的命令用root帳戶給root發一個郵件，結果失敗了。。。
# telnet localhost 25
Trying 127.0.0.1...

查看隊列：
# postqueue -p

(connect to mail.test2051.com: Connection refused)
root@test2051.com
用postfix flush或者是postqueue -f都沒法發出去。。。。求問該如何解決。
《解決方案》
現在是能發出去了。
修改了main.cf
將
inet_interfaces = localhost
改成了
inet_interfaces = all
這樣就可以發出去了。但是mail命令輸入后，提示No mail for root

《解決方案》
在main.cf中加了一句：
smtp_helo_name = $myhostname
解決了。
搜了下，， chifeng說是"兩邊"的hostname一樣了。http://www.extmail.org/forum/thread-19832-1-1.html
但不知道是那兩個hostname
參考：http://www.xiaojb.com/archives/mailtech/lookbacktomyself.shtml
這個文檔說是master.cf和main.cf上面是一致了。。。。。
