我一直在尝试让 sendmail 使用 zen.spamhaus.org 作为 dnsbl。我尝试了Crynwr 测试然后它给我发邮件说它失败了。我收到一封邮件说，Uh-oh, your SBL block is not working!
第二封邮件说，
I connected to 24.238.61.107 and here's the conversation I had:

Successful termination. As far as I can tell, the email was delivered.
That might not be what you want.

答案1
我不是 sendmail 专家，但我可以提供一个工作配置示例（通过 telnet 在 crynwr 上测试过）。取自我的一台旧 RH 服务器，因此可能状况相当糟糕。此外，您还应该考虑 sendmail 配置文件中的选项顺序可能是导致问题的罪魁祸首。
