[Mailman-Users] "from" column question--how can we get our name to appear instead of the email address?

Hello:

We are trying to send out a mailman message. When people receive our message, the mailman email address is listed in the from column and people think it's spam. How can we make it so that the name of the person posting is listed in the from column?

When I send messages from my Outlook account to any other address its says my name in the From box. When I send messages to the mailman listserv it lists the email address of the listserv in the From box.

Please help!

Thanks
