I have installed and configured Postfix and Cyrus IMAP server with webcyradm according to this document – http://www.delouw.ch/linux/Postfix-Cyrus-Web-cyradm-HOWTO/html/index.html .
I can access webcyradm interface, I can create new domains and new users, and I can login via IMAP after creating the user account.
However, Postfix fails to deliver mail to cyrus mailboxes. Mail log contains errors shown below. Installing any IMAP server other than cyrus is not an option because it is needed by the web application. Please advise me how to make Postfix deliver email to cyrus mailboxes. The solution should not necessary include web-cyradm, but there should be a web interface for managing mail domains and mailboxes as user-friendly as possible.

Best Answer
The user you are mailing to does not exist. See the log entry:
verify_user(user.imap0001) failed: Mailbox does not exist.And as you obfuscated the log, one can not be sure that this is the same or a similar error:
550-Mailbox unknown.
