针对 POP3 和 SMTP 使用 TLS 的 stunnel：配置是？

  • 772

在 SSLv3 上成功使用了 stunnel 多年。简单配置适用于较旧的 stunnel 和 SSLv3：

[noteworthypop]
accept  = 110
connect = secure.emailsrvr.com:995

[noteworthysmtp]
accept = 25
connect = secure.emailsrvr.com:465

但是，由于 rackspace 关闭了 SSL v3，因此此配置对我不起作用。

我们更新到当前的 stunnel (5.07)，它支持 TLS。我们在 Windows 2008 服务器上运行 stunnel。

上面的conf不起作用。添加协议行没有区别。例如

[noteworthypop]
client = yes
accept  = 110
connect = secure.emailsrvr.com:995
protocol = pop3

[noteworthysmtp]
client = yes
accept = 25
connect = secure.emailsrvr.com:465
protocol = smtp

尝试弹出时，日志显示：

2014.11.06 14:25:01 LOG7[2800]: Service [noteworthypop] accepted (FD=356) from 192.168.110.203:62058

2014.11.06 14:25:01 LOG7[3232]: RFC 2595 detected

但它坐。pop 客户端没有任何动作，没有任何反应。

欢迎提出建议！

谢谢！

    答案：尝试很多事情，直到有效果为止。

    “协议”条目实际上破坏了一些东西。

    这有效：

    [noteworthypop]
client = yes
accept = 110
connect = secure.emailsrvr.com:995


[noteworthysmtp]
client = yes
accept = 25
connect = secure.emailsrvr.com:465
