I have created a distro list, email@example.com and added two users firstname.lastname@example.org and email@example.com and tested all works fine. Then I deleted firstname.lastname@example.org because they left and when I send mail to email@example.com I get a bounce message stating firstname.lastname@example.org does not exist. I check the distro list and infact email@example.com 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?
