list questions

[Brian Sammon]

Okay what's the difference between arla-drinkers@ and arla-drinkers-list@ ?
Is it the same set of people subscribed to both?
One seems to get all the on-topic messages and the other seems to get all the 
spam and viruses.
One has a Sender: header that I can use to filter the messages with, the other 
doesn't.

I'd like to unsubscribe from arla-drinkers-list, but stay on arla-drinkers.
Is that possible?
