Add postfix to your cyrus group (which has the cyrus user).
This should do it.

These are different approaches!

Differences between the two postfix-transports "lmtp" and "cyrus" (they
are defined in master.cf of your postfix mailer):

"lmtp" uses the (L)ocal (M)ail (T)ransfer (P)rotocol to deliver mails.
Cyrus has an lmtp daemon (lmtpd) to accept mails. This daemon is invoked
at startup by cyrus-master (and can be preforked for high load
environments).

"cyrus" uses a pipe transport, invoking "deliver" for each mail
received. "deliver" itself is a little cyrus programm passing the mail
via lmtp to the lmtpd daemon. In Germany you would say "this is like
going with the church around the village" (mit der Kirche ums Dorf).

IMHO is the first one the more elegant way.
