SSL证书已导入java密钥库。
这里有什么问题？
telnet host port正在与客户合作。
答案 0 :(得分：1)
您正在尝试与纯文本POP3端口建立SSL / TLS连接，而不是POP3S端口。
因此，如果您想使用SSL / TLS，则必须启用starttls但禁用ssl。
props.setProperty("mail.pop3.ssl.enable", "false");
props.setProperty("mail.pop3.starttls.enable", "true");
props.setProperty("mail.pop3.starttls.required", "true");
