有一些使用端口465进行安全连接的SMTP服务器，但是，当使用TcpClient连接到该端口上的这些服务器时，没有发送欢迎消息，请问我在连接后立即确保连接的安全吗？

465 is meant for STMP over SSL, you'll have to establish an SSL connection before the SMTP conversation even starts, otherwise you won't get anything back, including a greeting banner. 
465适用于基于SSL的STMP，您必须在SMTP对话甚至开始之前就建立SSL连接，否则您将一无所获，包括问候语。 TLS works differently by starting a conversation and then encrypting. TLS通过启动对话然后进行加密来以不同的方式工作。
