No 
I dont use autocreate inbox. And as I have said lmtp accepts mail for
the same ids most of the times. One in every ~300 mails bounces
unexplicably 
 
I am now doing a dumb thing of running postfix on the cyrus box too to
accept the mails and relay to unix lmtp. This is loading the already
loaded cyrus server ( with approx 20000 active acounts ) .. but atleast
clients dont get bounced messages from my bosses id. 


This has surely got to do with the load on the cyrus machine. But
returning 550 when machine is loaded is a *really* dumb idea.
