[Mailman-Users] Messages silently disappearing

[Wes Morriston]

Hi again.

I did a 

   ls -ld /home/mailman/data

and got this.

   drwxrwsr-x   2 root  mailman       512 Feb  9 17:37 data

That is exactly how mailman installed itself.  (I was root when I did
the install.)

I then did a

   chown -R mailman .

in /home/mailman.

It made no difference.  Messages still silently disappear unless python
is set to run as root.

The following, I discovered, does cause the messages to be delivered.

   chmod +s /usr/bin/python

I hope it is not too dangerous to run python as root.

Wes
