[Clients] Server instability

[Steve Hanson]

Those of you with web sites or email on miserver1 may have noticed 
several server downtimes in the last few days.  We finally tracked this 
down to a network of spambots that are attempting to post spam on one of 
the the web sites on the server.  We've done some creative blocking of 
IP addresses, and changed some web server parameters - this seems to 
have made the server much more stable, and it went through another such 
attack last night without hanging up.

We apologize for the issues, but I think this is now resolved, and 
should make the server degrade much more gracefully when under attack.   
Things should be much more stable from now on.
