Sorry, I meant bug-...@nongnu.org and help-...@nongnu.org. It is currently not possible to use them, since the web interface forces you to use foo-whate...@nongnu.org.
Well, I tried, but after half an hour of frustration, I don't want to spend more time on it, sorry. Michael? Evidently savane-cleanup/frontend/php/include/Group.class defines a function getTypeMailingListFormat which returns the list of allowed names. The critical data comes from $this->type_data_array['mailing_list_format'] but I could not figure out where that list comes from / is defined. The database? (Then savane-cleanup/frontend/php/mail/admin/index.php generates the HTML.) karl
