为什么sendmail的PO3端口110能够telnet,smtp端口25却被拒绝？

bigsw

sendmail安装好后,telnet 110端口,无论是localhost , localhost.localdomain还是dns解析的域名及ip都成功,但telnet 25端口只有在telnet localhost 25 或是localhost.localdomain 25 或是127.0.0.1 25 才成功,用它的完整机器名及它本身的ip去telnet 25端口时去出现被拒绝的情况,我怀疑是/etc/mail/access 与/etc/mail/access.db没有转换好!望给位大虾指点!!

我的主机名为test,域名为3322.org
redhat 7.3+sendmail8.11+iamp-2001a-10
我已经建好了dns解析
完整机器名: test.3322.org IP: 10.10.10.12

telnet localhost 25
telnet localhost.localdomain 25
telnet 127.0.0.1 25
都是没问题的,但是telnet具体的域名和ip的25端口时,却出现拒绝的现象,能够ping通,我已经执行过#makemap /etc/mail/access.db < /etc/mail/access

/etc/mail/access

检查一下你的xinetd或inetd的配置文件。

Glue

是sendmail本身的设置。
要找到sendmail.mc，修改以后重新生成sendmail.cf文件才可以。

wjs

在sendmail.cf里面添加一段
O DaemonPortOptions=port=smtp,Addr=xxx.xxx.xxx.xxx,Name=MTA
注意上面的x代表你的ip地址，原来的文件里面只有127.0.0.1的，不是对外的！

谢谢各位弟兄,

经过我反复测试,glue兄和wjs兄说的情况都有可能产生我所说的错误.

总结一下:
1)必须修改sendmail.mc中
O DaemonPortOptions=port=smtp,Addr=xxx.xxx.xxx.xxx,Name=MTA
127.0.0.1到0.0.0.0
2)必须成功地用m4命令将sendmail.mc编译成sendmail.cf,然后重启sendmail服务.

也许是个很菜的问题,但只要是问题总会给人启示,谢谢各位兄弟.
