qq收不到oracle邮件 腾讯企业邮箱发送邮件失败

一直使用的腾讯企业邮箱，但是最近发现发送邮件全是失败的，提示：

javax.mail.MessagingException: Could not connect to SMTP host: smtp., port: 25;

nested exception is:

.ConnectException: 连接超时 (Connection timed out)

at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:1961)

at com.sun.mail.smtp.SMTPTransport.protocolConnect(SMTPTransport.java:654)

at javax.mail.Service.connect(Service.java:317)

at javax.mail.Service.connect(Service.java:176)

at javax.mail.Service.connect(Service.java:125)

at javax.mail.Transport.send0(Transport.java:194)

at javax.mail.Transport.send(Transport.java:124)

修改端口后又有一下错误：

javax.mail.MessagingException: Could not connect to SMTP host: smtp., port: 465, response: -1

at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:1949)

at com.sun.mail.smtp.SMTPTransport.protocolConnect(SMTPTransport.java:654)

at javax.mail.Transport.send0(Transport.java:194)

at javax.mail.Transport.send(Transport.java:124)

这个是少了一个配置mail.smtp.ssl.enable=true，在原来的配置上加上这个就OK了。
