You could modify the above to write the list to a file and then wrap the
whole thing in a shell script which would make the list and then do
something like
for f in find var/messages -type f;do
n=cut -d / -f5 &lt;&lt;&lt;$f
for keep in cat list ;do
k=0
if [ $n == $keep ] ;then
k=1
break
fi
done
if [ $k -eq 0 ]; then
rm $f
fi
done
Actually, I thought about it a bit more, and I decided that arcane shell
script was a bit obscure and it would be easier to just do it in Python.
Plus, you can properly delete the message that way.
A complete script for mailman shell is like
import os
msg_ids = {}
lm = getUtility(IListManager)
ms = getUtility(IMessageStore)
for mlist in lm.mailing_lists:
requestdb = IListRequests(mlist)
for rq in requestdb.held_requests:
key, msgdata = requestdb.get_request(rq.id)
if msgdata['_request_type'] != 'held_message':
continue
msg = ms.get_message_by_id(key)
msg_ids[(msg['Message-ID-Hash'])] = True
for root, dirs, files in os.walk('path/to/var/messages'):
for file in files:
if not msg_ids.get(file, False):
msg = ms.get_message_by_hash(file)
ms.delete_message(msg['Message-ID'])
