Fedora email autoresponder with GUI?

http://forums.fedoraforum.org – Can anyone recommend an email follow up autoresponder, with a nice GUI please? Something that would make setting up and managing mailing lists a breeze? I've looked at http://www.aweber.com/videos.htm but this is a commercial web-based emailer. Is there anything like the above that's free to use and runs on Linux? (HowTos)
