[imp] imp list dnscache

[Robert Clemens]

Actually it's interesting now that I look at it. After scrolling through my 
messages. (I have quite a few). I found two emails from the imp mailing list 
that went to the new server and the rest goto the old server. And I just 
recieved right before writing this email another email from the IMP list to 
the new server. I'm not sure why it's switching back and forth on me. Could 
it have both ip's cached and be picking them from there?
