找不到maildrop...

cycle14

系统FC3＋postfix＋cyrus-imap。 postfix没有问题能发信。但收信时弹出错误信息： "Unable to locate maildrop for userXXX: Mailbox does not exist". maillog记录:

我的 imapd.conf 文件:

configdirectory: /var/lib/imap
partition-default: /var/spool/imap
admins: cyrus
sievedir: /var/lib/imap/sieve
sendmail: /usr/sbin/sendmail
hashimapspool: true
sasl_pwcheck_method: saslauthd
sasl_mech_list: PLAIN
tls_cert_file: /usr/share/ssl/certs/cyrus-imapd.pem

tls_ca_file: /usr/share/ssl/certs/ca-bundle.crt

我的邮件存在 /var/spool/mail里，有问题吗? 我的postfix是在图形界面用mail transfer agent转的。
