It utilises a few patches made by Andrzej Filip, namely

http://www.polbox.com/a/anfi/sendmail/rtcyrus.html
http://www.polbox.com/a/anfi/sendmail/_FFR_MAP_FSTAT.html
and if you want it
http://www.polbox.com/a/anfi/sendmail/localNalias.html

Basically it assumes that the IMAP server is present on the same
machine. Then it executes a fstat on /var/spool/yourimap/users/<username>

After ALL expansion has been finished and all virtual look ups finished.

As I said, if you want details and I see some feedback, I am willing to
write a howto
