working on it, spent a few hours yesterday and today to work on our
filtering but it is not as easy as simply declaring "everything that is
a very short mail and has a url in it is bad".
We do have regular mailbox users (in the same namespaces as the list) as
do we have lists that want to receive such stuff (say the sysadmin list
getting an email about a failed http download from a cronjob with
basically just the url).
