Email Thread Messages using JavaMail API

But Still could not find proper way of implementing this. have anyone succeeded in doing this. I know we need to have this "algorithm thread" implemented but how we could implement. as I am using JavaMail version 1.5.6.

CodePudding user response：

There is no proper way of doing that. Sometimes your server does not have compulsory extensions installed in it. for your issue you must have sort and thread extension installed in it.
