在SSLv3上成功使用了stunnel。 简单的configuration适用于较老的stunnel和SSLv3：
[noteworthypop] accept = 110 connect = secure.emailsrvr.com:995 [noteworthysmtp] accept = 25 connect = secure.emailsrvr.com:465 但是，现在该机架closuresSSL v3，此configuration不适用于我。
我们更新到目前的通讯（5.07），它有TLS的支持。 我们在Windows 2008服务器上运行stunnel。
以上conf不起作用。 添加协议线没有区别。 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
当试图popup时，日志显示：

但它坐。 stream行的客户端没有任何动作，没有任何反应。
build议欢迎！
谢谢！
答案：尝试很多东西，直到有效。
“协议”条目实际上破坏了事情。
这工作：
[noteworthypop] client = yes accept = 110 connect = secure.emailsrvr.com:995 [noteworthysmtp] client = yes accept = 25 connect = secure.emailsrvr.com:465
