	One other note -- watch your maximum message size that you allow 
to be posted to the list, as well as the attachments and MIME 
bodypart types.

	If you have a list of 250 company employees, and some moron in 
marketing sends a 50MB PowerPoint presentation to the 
all at lists.company.com mailing list, that works out to about 12GB of 
disk storage that you have to suddenly find to store all 250 copies 
of that 50MB attachment, and a hell of a lot of disk I/O to write all 
that out at once.


	I worked at a local ISP that had a mail server for 250,000 
customers that was completely nuked in this way by one of our own 
marketing dweebs, and the machine only had something like 8GB of disk 
space free.  The entire mail server was down for hours as I tried to 
clean things up and to purge all the bogus copies of that 
presentation.

	You can imagine how upset all the 250,000 customers were that the 
mail server was down.


	Trust me, you don't want to have this happen to you.
