      This milter rejects the recipient, don't use milters that reject recipient
      addresses you want to receive. Milters process the original address from
      the RCPT TO: command, not the results of alias expansion. Perhaps your
      milter is expecting something else.

      Don't blame the messenger, Postfix is just reporting the milter
      verdict. This sure does not look like a Postfix problem.

        j-chkmail (and most milters) doesn't access any user table (aliases, ...). It
        can do recipient verification if you tell it to do (sometimes useful on a
        gateway). In this case, you shall maintain a table of valid recipients. IMHO,
        this feature is useful on a zimbra server only if it is on a border of your
        domain and you want to detect address harvest.

        If this may be your problem, please post j-chkmail logs related to this, and
        post a question to me or to j-chkmail users list as this isn't a postfix problem.
