In your master.cf, at the end of the lmtp line, add "-v".  That will cause 
the Postfix lmtp client to run in verbose mode.  This might help to track 
things down.

Also turn up the logging of Cyrus to debug and see what is recorded there. 
In general, the more logging, the easier it is to track these sort of 
things down.

Next, it is a bad idea to use anything under the Postfix hierarchy for 
3rd-party software.  While public/lmtp is probably okay, I think it is best 
to simply not fiddle with anything under there---less possibility for 
surprises.

Finally, make sure that both the Postfix user and the Cyrus user are able 
to access this named pipe.  This means temporarily assigning a shell to 
these two users, doing an su to them, and make absolutely certain that both 
can access this file.

Yeah, but if you're using a stock install, that ultimately uses the deliver 
command, which will incur a bit more overhead.  Using lmtp directly is a 
better way to go if at all possible.
