I am the group moderator. I would like the emails from the group to display the group name; not my email. How?

it depends on where you post from, the group or your e-mail. if you post from the group, on the group will have your ID however when it goes out to individual mail it will have your e-mail address that you have selected to use, there is no way around that. the group title is in the subject line of all posts, and there is no way to have the group title as your e-mail instead of your own unless you make an ID using the group title
