我正在管理专用邮箱。最近几天我的服务器 IP 被 hotmail 服务封锁了。我的客户无法向 hotmail/live/outlook 系统发送任何消息。
postfix ver: 2.6.6
CentOS 6.4 64 Bit
I just Installed MailScanner and Clamd latest version
以下是我的开放中继报告：

答案1
从今年起不再受支持意味着不存在风险。我认为 CentOS 维护人员会反向移植安全修复程序。
您的邮件问题通常是由服务器配置不当造成的。请进行开放中继测试，并将您的服务器配置为不发送垃圾邮件。如果情况没有改善，则您的服务器已受到威胁。
