Ticket creation via Email is not working

Question

I have upgraded my JIRA to 6.3.1 however my ticket creation via email is not working. I've configured the mailbox and mail server.
When i do the testing it shows ticket creation is successful but it doesn't create ticket neither it deletes it from the mailbox.
