You can't.  Cyrus virtuously replaces /var/spool/mail.  Postfix
delivers mail into Cyrus, which stores it - and the **ONLY** way mail
is accessed is via Cyrus (IMAP, POP, JMAP).

You should configure Postfix to deliver to Cyrus via LMTP (local mail
transport protocol).

mailbox_transport = lmtp:unix:/var/lib/imap/socket/lmtp

[root at aleph ~]# fuser -u /var/lib/imap/socket/lmtp
/var/lib/imap/socket/lmtp:  4611(cyrus) 23327(cyrus)

I haven't used deliver in decades.  Using LMTP avoids all the hazards
of old-school 'file processing'
