Summary says all, unofficial archives are missing some lists (for example gentoo-doc-de@g.o), patch against current cvs attached.
Created attachment 104804 [details, diff] patch for lists.xml
I'll take this one, since I'm part of GDP who are CCed on it anyway, and I'd like to think I'm helping infra by getting all the tiny pesky bugs out of their way so they can focus on bigger issues. :) (if not, you may swat me.)
Thanks for reporting and for the patch. Fixed in CVS.
