[kwlug-disc] clearing close_wait

Seems lately I've been enjoying somewhat frequent attacks on my mail 
server.  Some IP address opens up a thousand email connections on my 
server, no idea why.

I firewall the IP address, but I still end up with a ton of connections 
in a CLOSE_WAIT state.  Is there any way to clear those all those 
close-wait connections from the offending IP, without rebooting?  If I 
leave it sit they eventually all go away, I'd like a faster solution though.
