Here are my rules for mailing lists catchall:

if header :matches "List-ID" "*<*.*>" {
  fileinto :create "${folder}/${3}/${2}";
  addflag "DeliveredTo" "$${dflag}";
} elsif header :matches "List-ID" "*<*>" {
  fileinto :create "${folder}/${2}";
  addflag "DeliveredTo" "$${dflag}";
} elsif header :matches "List-ID" "*.*" {
  fileinto :create "${folder}/${2}/${1}";
  addflag "DeliveredTo" "$${dflag}";
} elsif header :matches "List-ID" "*" {
  fileinto :create "${folder}/${1}";
  addflag "DeliveredTo" "$${dflag}";
} elsif header :matches "List-Owner" "<mailto:*-owner@*>" {
  fileinto :create "${folder}/${2}/${1}";
  addflag "DeliveredTo" "$${dflag}";
} elsif header :matches "List-post" "<mailto:*@*>" {
  fileinto :create "${folder}/${2}/${1}";
  addflag "DeliveredTo" "$${dflag}";
} elsif header :matches "List-owner" "<mailto:*-request@*>" {
  fileinto :create "${folder}/${2}/${1}";
  addflag "DeliveredTo" "$${dflag}";
}

Due to copy and paste I had some rules like

} elsif header :matches "List-Owner" "<mailto:*-owner@*>" {
  fileinto :create "${folder}/${3}/${2}";
  addflag "DeliveredTo" "$${dflag}";
} [...]

The bad rules only triggered on very few mailing lists (those that
don't use proper List-*: headers), so I only noticed a couple of days
later. IIRC two of the lists were bugzilla and scientific-linux.

E.g. the fileinto was probably given some argument of "lists//somedomain.org"

Does this information help?
