How can i know about all email address that are receiving email notifications related to my JIRA instance whether they are internal or external use'r of my origination.

or you could Export the user data, which contains the mail address.
In this case, you would get all possible addresses to which jira could send a mail.

You can find this information in the logs (jira-outgoing-email.log). The only work is to get this information and later do something with it..

Or install addon that would do the same but in the UI.. Example:
