How to change the body of email notifications in Redmine?

Question

Email

Good afternoon.
There was a need to edit the body of notifications sent to users by e-mail from Redmine. Namely, how to make it so that users receive a simple notification of an event without attaching the event itself (correspondence, comment) of the task? It is necessary that the user receive notifications like:
"User Vasya commented on the task assigned to you. Details at the link ...."
By default, the system sends all correspondence. As a result, some individuals (users) respond to this letter with a reply letter.
Thank you!

No one asked this question? Give, pliz, a tip where to dig or what template file is in the system?

See: /redmine/app/models/mailer.rb
For example New Task Notifications:

# Builds a mail for notifying to_users and cc_users about a new issue
  def issue_add(issue, to_users, cc_users)
    redmine_headers 'Project' => issue.project.identifier,
                    'Issue-Id' => issue.id,
                    'Issue-Author' => issue.author.login
    redmine_headers 'Issue-Assignee' => issue.assigned_to.login if issue.assigned_to
    message_id issue
    references issue
    @author = issue.author
    @issue = issue
    @users = to_users + cc_users
    @issue_url = url_for(:controller => 'issues', :action => 'show', :id => issue)
    mail :to => to_users.map(&:mail),
      :cc => cc_users.map(&:mail),
      :subject => "[#{issue.project.name} - #{issue.tracker.name} ##{issue.id}] (#{issue.status.name}) #{issue.subject}"
  end
