Email List Software like Topica.
 

I belong to a group that just cannot seem to get away from email.
They have been using Topica for a couple of years now, and lately the service has turned to shit.

I am wondering if anyone knows of any good software where I can run this email list off of one of my own servers instead.

Thanks in advance.

Hmm..don't know if that's what I need.

The users on the email list must be able to send an email to the entire group.
