[imp] imp list dnscache

[Robert Clemens]

I'm not sure where else to send this but how long does lists.horde.org cache 
hosts for? I recently switched my domain to another mail server I setup and 
I'm still receiving imp list mail on my old server. Just trying to find out 
how long I need to keep the old server up. I think it's been a couple days 
so far. Any idea on this would be appreciated. Thanks!
