Currently Jira notification includes most of the fields of view screen. However, can we modify Jira notification mail for few fields only for one project?
If you were in a Standalone, you could customize the mail template vm files at $JIRA_INSTALL/atlassian-jira/WEB-INF/classes/templates/email directory. You would find vm files for each event in JIRA and one folder for text emails and another folder for html emails. However, I believe that there is no way to apply this changes for only one project.
You can find more information at Customizing Email Content page.
