It isn't that bad, really :)

Ahhh!  I forgot about the squatter, yeah with that you get the body indexes 
if you want ot search on teh bodies of messages.  There are some scripts to 
'continuously' run squatter (really a set of cron scripts that cause it to 
run for about a minute or so then continue on...getting started and stopped 
every few minutes)

But as I said in my previous post, all the other indexes are maintained, 
and newer versions also maintain a 'threading' index that smarter IMAP 
clients will take advantage of (Evolution, mulberry....not sure of what 
others, probably PINE heh)
