try
sendmail -bv -d60.5 -d27.2 -d21.12  gcr+detail at badger.tharned.org

- -d60.5 - trace map lookups
- -d27.2 - traces processing of aliases and forwards
- -d21.12 - trace R line processing

IMHO: If all map lookups return NOTFOUND, the detail is preserved, 
otherwise it is the duty of the map to preserve the detail.
