I would like JIRA to send emails using the name and email address of the user who actually made the comment or changes to the issue ticket. Currently JIRA sends emails using the default email address specified in the SMTP server settings or project defaults.

There should be a config option to do so.

For e.g., If the user John Doe makes a comment, the assignee should get a notification from john.doe@company.com instead of generic support@company.com.
