This page offers indices by Date, author or subject as well as a search
engine (currently only available in Aachen and St. Andrews.) Searching for
example for 'TRANSDGEGREES' yields the above mentioned mail as the only result.
The bug (among many others) is fixed in the recent release 3.4.4, so you
should take the opportunity and upgrade.
