telnet 127.0.0.1 25 通过
telnet IP 25    Connection refused

注释已经去掉
DAEMON_OPTIONS(Port=smtp,Addr=127.0.0.1,Name=MTA)

基本情况:

   两台机器.
      adf36.you.com 192.168.0.36
cs100.you.com 192.168.0.100

adf36是DNS server
nslookup 情况
> set q=mx
> you.com
Server:       192.168.0.36
Address:       192.168.0.36#53

you.com mail exchanger = 5 adf36.you.com.

还是只监听127.0.0.1的25端口啊,没改好.

hnull · 发表于 2005-3-10 19:28:39

楼上说得对

cyy911 · 发表于 2005-3-10 23:02:35

确实是这个问题。
茅塞顿开。
谢谢各位。谢谢。

cyy911 · 发表于 2005-3-10 23:11:41

这个问题是这样的。是我自己没有读懂为什么，而是按介绍照做的
DAEMON_OPTIONS(Port=smtp,Addr=127.0.0.1,Name=MTA)
如果不注释也就是默认情况是只对本地侦听。应该把他注释掉，就可以对所有进行侦听
用netstat -lnt
会出现
0。0。0。0：25

另外有谁知道
dnl作为sendmail.mc的注释放在语句的前面和后面有什么区别吗？？
也就是说
dnl DAEMON_OPTIONS(Port=smtp,Addr=127.0.0.1,Name=MTA)
DAEMON_OPTIONS(Port=smtp,Addr=127.0.0.1,Name=MTA) dnl

放在后面表示该行仍未结束，我记得是这个样子的，不是太肯定。
