Please see <https://wiki.list.org/x/12812344>

That said, Assuming the Mailman user is 'list' as it normally is in a
Debian package installation, the mode and ownership of
/var/lib/mailman/data should be

drwxrwsr-x 3 root    list

Owner (root in this example) doesn't matter, but group 'list' and SETGID
are important. aliases(.db) should be

-rw-rw-r-- 1 root    list ... aliases
-rw-rw-r-- 1 list    list ... aliases.db

Again the owner of aliases doesn't matter but the owner of aliases.db
and the group of both should be 'list'.

Also, all the wrappers in /usr/lib/mailman/cgi-bin/ should be group
'list' and SETGID.
