这是一个创建于 3550 天前的主题，其中的信息可能已经有所发展或是发生改变。
背景:基本完全不懂linux,最近在学习zabbix.发信告警功能需要本地邮件服务器.只要发信不需要收信
经过:网上查了一堆,试了一下午都没有成功,对自己的智商绝望了.
服务器上postfix本来就是装好的,我就改了一下main.cf文件,下面是我改的地方:
myhostname=mail.test.com
mydomain=test.com
myorigin=$mydomain
inet_interfaces=all
mydestination=$mydomain,localhost.$mydomain,localhost,$mydomain
mynetworks=192.168.0.244,127.0.0.1
relay_domains=$mydestination
然后按网上说的测试:telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 mail.test.com ESMTP Postfix
421 4.4.2 mail.test.com Error: timeout exceeded
Connection closed by foreign host.
之前还改了一些地方，记不太清了，这是最后的结果，之前的结果是没有倒数第二行和倒数第三行。
请大家指点一下，是这么设置吗，哪儿出错了
疑问：如果只发信不收信，只用postfix能实现吗
而且zabbix添加邮箱时没发现能添加密码，我在想能实现发信的时候直接发不用密码吗
跪谢啊

Postfix 默认起来什么都不用改就可以发信了。不信你可以用 `mail -s 'test mail' [email protected]`发一封信试试，不过发信地址是 [email protected]。

用 mail 写完信以后 CTRT+D 结束，才会发送。

另外注意查收“垃圾邮件”。

delavior OP @kidlj 抱歉，再问一个问题，我发送的正文怎么收不到啊.
[root@test ~]# mail [email protected] Subject: test mail 2 Hello,this is a test mail . EOT 上面是发信的命令，结果收到的邮件只有主题，没有正文，试了好几遍都是这样。请问发信的命令不对还是还需要配置别的？ |
