Different e-mail "from" field for projects

[piotrch]

Hi.
Is it possible to set a different "from" field per project?
I use EmailReporting plugin for one of my Mantis projects and I would like to send all notifications for the project using the different field "from".
Now, when somebody write a comment in project I receive a notification from main e-mail address.
Is it possible to change it?
If yes, how?
Could you help me?

Peter.
