使用QQ邮箱收发邮件遇到的坑有些WIFI不支持ipv6

使用QQ邮箱发邮件，首先要开启SMTP授权码。

在邮箱的账户安全设置里面

但是某些WIFI报错

sendText failed port 587: Couldn't connect to host, port: smtp.qq.com, 587; timeout 10000

com.sun.mail.util.MailConnectException: Couldn't connect to host, port: smtp.qq.com, 587; timeout 10000;

nested exception is:

java.net.SocketTimeoutException: failed to connect to smtp.qq.com/2408:8756:f50:4::7c (port 587) from /2408:8256:c82:3ddc:c86d:db1c:f147:9836 (port 49116) after 10000ms
