Redmine

I need to set a custom email sender per project. There used to be plugins for very old redmine versions, but these don't work with current versions any more:

https://github.com/Warecorp/redmine_project_specific_email_sender
https://github.com/eashman/redmine_author_notification_emails

My current solution is to add a custom mail_from field to projects and patch app/models/mailer.rb like this:

678a679,686
>     # CE: project specific mail from address
>     if @issue
>       new_mail = @issue.project.custom_field_values[0].value
>       if !new_mail.nil?
>         headers.merge!('From' => new_mail)
>       end
>     end
> 

I'm wondering if someting like this could be add to redmine.
