I'm currently sucking, with fetchmail, from a dovecot database at my isp, 
but the procmail direct deposit into the spam folder, which gets mv'd to 
spam-hold for one day by the same script that has sa-learn spam being 
done on that folder, moving what it has looked at to spam-hold.  Thats 
the only non-kmail accesses that I have programmed.  Any other incoming 
mail is deposited in /var/mail, and dbus sends kmail a check local 
folder message for new mail by way of inotifywait seeing the closing of 
the mail file and triggering the dbus message.  The 
locale /var/mail/mailfile generally has a lifetime in the non-zero 
length state of milliseconds.

describe that please.

procmail may, very occasionally place a particularly nasty bit of stuff 
directly in the spam folder, but thats not more than a weekly 
occurrence. If that often. I'll find that recipe and nuke it, just for 
S&G.  Or better yet, send that one to /dev/null. At least I'll have a 
log entry. Right now, I think I'll go over the /home/gene/Mail dir and 
nuke every sorted index just for S&G as thats nowhere near universally 
present. Then I'll exit kmail as the uptime is 29+days, and restart it.
