Hi,

I'm writing to you about the bug you reported to Debian about
Mailman. (http://bugs.debian.org/339095)

I can't reproduce the bug as you describe it, at least the DOS
part. In my testing, messages with attachments with an invalid
filename:

 - _do_ get distributed
 - do _not_ get archived
 - generate a traceback much like yours
 - do _not_ DOS the list: subsequent (valid) messages get delivered
   and archived correctly.

The "do not get archived" part is still a bug, one that will
(hopefully) be fixed with the next Debian upload. But if they don't
DOS the list, it is not a security issue and doesn't warrant a
security update to Debian stable.

I used exactly the filename you put in your bug report for my
testing.


If you have a message that DOSes a list, would be so kind as to send
it to mm-test@tofu.mamane.lu and notify us at
pkg-mailman-hackers@lists.alioth.debian.org ? I fear that the DOSing
comes from a different issue than the filename encoding, and in that
case I'd like to investigate it.


Thank you in advance,
