I don't know if it does or not.  But IMHO, the best way to do this is to 
use the socket map support in Sendmail 8.13 (a patch is available for 
8.12) and smmapd in Cyrus 2.2.  This eliminates the need to peek into 
the imap spool and will support whatever mailbox namespace and/or spool 
hashing that Cyrus is using.
