I have created a distro list, firstname.lastname@example.org and added two users email@example.com and firstname.lastname@example.org and tested all works fine. Then I deleted email@example.com because they left and when I send mail to firstname.lastname@example.org I get a bounce message stating email@example.com does not exist. I check the distro list and infact firstname.lastname@example.org is still there. I will have quite a few different lists and maintence is going to be a chore if the lists dont "self clean". Am I missing something?
