I've no idea if mailman has own special tools for that,
standard Unix tools can find tools that use the Unix find command, eg
	echo "Learn find, dialects vary per Unix."
	man find 
	cd /usr/local/mailman/bin 
	echo "Get an idea where to look:"
	find . -type f | sort | xargs grep -l find | more
	find . -type f | sort | xargs grep -l find \
		| grep -v /archives/ \
		| grep -v /lists/ \
		| grep -v /logs/ \
		| grep -v /messages/ \
		| grep -v /templates/ \
		| grep -v /tests/ \
		| more
	echo "Ignore ./cgi-bin/* binaries."
	vi -c/find `find bin/* scripts/* -type f | xargs grep -l find`
	echo "Also consider ./Mailman/*/*.py[c] files"

Or more simply:

cd /usr/local/mailman/archives
find . -type f -name \*.html | more

so eg
	rm -rf ./private/pc532/2007*

find . -type f -name \*.html | xargs ls -l > ~/tmp/dates_to_browse
find . -type f -name \[0-9\]\*.html
find . -type d -name 2012q\* | more
find . -type d -name 2012q\* | xargs rm -rf

Find is very powerful.  Read 
	man find
before you use find,
before you use
Do a backup before anything.
