[Mailman-Users] Problem after upgrade to mailman-2.1.30-1

Hi Mark: After upgrade to mailman-2.1.30-1 when I create a new list, the list is created correctly in the alias file and in virtual-mailman file, but the new list does not work until I run the command /usr/lib/mailman/bin/genalises. Any ideas? Thank you very much as always for your invaluable help.
