Forum Notification Emails: Customization

Currently, at the end of each forum notification email, it ends with a line like:

To view the forum comment, login to
https://projects.zoho.com/portal/mine#forums/#####/######

I would like to disable that when sending to the client, so that the client would only reply - and not click into the project. Or add my own custom footer per project.

Also, I'd like to customize the "from" line: "Project Name Notification"

Actually, I'd like to customize the entire email notification to suit my project/client needs.

thanks,
clark
