It did not, the whole list (including archive) was affected. The emails,
generated by charter.net's postmaster, had severly broken headers.

Note the unbalanced quotes, and I also believe that the end-of-lines
were not correct. This is obviously the reason why the filter did not
catch them. I also noticed a badness in the mime-type, which included
the error message. Again I think it's an issue with line terminators.
Thanks Phil for fixing the problem. Frankly there's nothing you could
have done IMHO, the headers were just too broken. One think I'm thinking
of though is that you could reject messages with empty subject. It would
at least have caught this one...
The responsability is definitely on charter.net's side. I e-mailed them,
no answer yet. I would certainly not recommend them to anyone...
Andrew, can you please delete all the offending mails from the list
archive? These are the ones who read "# [no subject] LM_Sensors
Development Group". These are adding noise to the list and are also
wasting your disk space with no benefit.
