Unwanted messages

[A J Stiles <deb64@earthshod.co.uk>]

We seem to be getting a lot of spam being sent to the list lately.  Can we do 
anything to block it?  Only accepting inbound mail from addresses on the 
recipients list would be a good start.  Also, since we're all Debian users 
here, it might make sense to reject mail apparently coming from a 
Windows-based user-agent.

It was ironically endearing when it was adverts for pirated Windows software; 
but I get enough pr0n, phishing and share scams elsewhere without them coming 
through this list.
