Hi Buyer,
This can be done with JVM, Here is my understanding.
When you hit with an email id, First it needs to check about the MX Servers, and try to send an email to that, So it needs to get a response from the recipient server that it has been received. Based on that we can confirm that email has been validated.
however there are couple of things involves here, that Reverse dns checks to identify the respective aspects and some servers does not give proper responses, in those cases, we may not be able identify the originality. hope that is fine.
One question, JVM means? Is it core java program you need or any web MVC like Spring MVC or JSP related service you are looking for?
Please confirm or lets have a discussion so that we can take it forward.
Thanks in advance and looking forward to hear from you.
