我正在尝试使用sendmail发送电子邮件。 我遵循这个方法： http : //linuxconfig.org/configuring-gmail-as-sendmail-email-relay
我试图通过控制台发送电子邮件：
echo "Just testing my sendmail gmail relay" | mail -v -s "Sendmail gmail Relay - New Server" user@gmailcom 命令的输出是：
WARNING: local host name (server01) is not qualified; see cf/README: WHO AM I? [email protected]...

221 2.0.0 server01closures连接但电子邮件永远不会到达。 你们能帮我吗？

Gmail拒绝接受您的电子邮件。

以root身份执行以下命令以详细模式发送testing消息
（你会看到SMTP会话logging）：
(echo Subject: test; echo; echo test)|/usr/sbin/sendmail -Am -i -v [email protected]
您可以将-d60.5添加到sendmail命令行选项（收件人地址之前）以跟踪包括authinfo查找在内的映射/数据库查找。
发送电子邮件给像gmail，yahoo，msn等大型服务器可能会非常棘手，因为通过反垃圾邮件防护要求所有configuration都处于完美状态。
您需要检查以下内容：
使用parsing为您的IP的实际域作为您的系统的主机名。 所以，而不是server01你应该使用your-company.com
请确保您的IP具有PTR DNSloggingconfiguration为parsing到您用于发送电子邮件（ your-company.com ）的相同的域
确保你已经为your-company.com configuration了SPF DNSlogging
确保你有DKIM的工作 ，密码唱歌从您的服务器的每封电子邮件。
这个步骤应该足以让你的电子邮件实际到达Gmail。
