sendmail默认不能发信

ccnuzxg

VMware下Centos 5.6 使用自带的mail命令发信无法收到信件

echo "这是一封测试邮件" | mail -v -s "Mysql 5.1手册" 281674669@qq.com

我用mail -v命令测试如下：

请各位帮忙看下是什么问题~


PS：后来我收到一些退信，

(Deferred: Connection refused by mx1.qq.com.)


连接拒绝，是什么原因呢？

懷疑是domain的關係，可能因 @localhost.localdomain 被mx1.qq.com給退的

嘗試sendmail 中的masquerading 定一個domain 試看看
