You don't need 0.0.0.0, just lmtp      cmd=lmtpproxyd listen:lmtp" will do.

Two things wrong here. First, you only need one line. lmtpunix is for
listening on a unix socket. lmtp is for listening on a tcp
socket--this is the one you need if postfix is on another server.
Also, the -a is telling lmtp to use preauthorized connections. This is
not what you've told Postfix. Get rid of it. Make sure you tell Cyrus
your lmtp password in imapd.conf.

So, lmtp       cmd="lmtpd listen:lmtp" prefork=1     will work.

See, Postfix is trying to send a username and password to authenticate
itself to Cyrus. Make sure they both have the same username and
password information.
