[Mailman-Users] Permission of data/bounce-events-?????.pck

[imacat]

Dear all,

    I was checking my system for world-writable files, and found lots of
data/bounce-events-?????.pck that are world-writable:

imacat at rinse ~ % ls -lt /var/lib/mailman/data | grep 'rw. '
-rw-rw-rw-  1 list list       0 2006-01-31 01:26 bounce-events-02258.pck
-rw-rw-rw-  1 list list    4786 2005-12-26 17:36 bounce-events-26086.pck
...
imacat at rinse ~ %

    I searched the archive and know that they can be safely deleted. 
But, is that "world-writable" intended?  I'm a little worry about it.
