提前感谢您的帮助。

您似乎正在连接端口465，该端口为。支持SSL 3.0，因此我建议改为连接到支持TLS的端口之一（而不是启用不安全的密码套件）。是的，但相同的代码在另一台机器上运行得很好。。。？此外，上面指定的端口为

port=587

…在一台机器上运行的代码可能在另一台机器上失败，甚至在同一台机器上的不同运行中失败。stacktrace表明它在任何情况下都连接到端口

，这就是为什么我认为它失败的原因，因为它试图协商一个不受支持的密码套件。尝试使用

tls=T

而不是（在MS Exchange服务器下）所示的

ssl=T

。从

ssl=TRUE

切换到

tls=TRUE

会产生相同的错误消息，但不是无法连接到端口

（如原始问题中所示），而是现在无法连接到

，至少现在你看到你没有连接到你以为是的端口。这就是为什么读取错误消息比读取配置值更有价值。为什么不运行代码以查看启用了哪些密码套件。
