Is there a way that I can use the e-mailaddress of a group for outgoing mail?

[Janny Roelfs]

I want to use the e-mailaddress of a group to send e-mail to members of my group but also to addresses outside my group. The recievers of the e-mail should recognize the group as the sender and is also able to reply to this e-mailadress.
