求救POSTFIX邮件系统可以发送邮件但无法接收邮件

[weixin_38058663]

请教各位兄弟

近期在LINUX AS5平台安装了POSTFIX邮件系统，安装的包如下：
postfix-2.3.3-2.i386.rpm
perl-DBI-1.52-1.fc6.i386.rpm
mysql-5.0.22-2.1.i386.rpm
postgresql-libs-8.1.4-1.1.i386.rpm
dovecot-1.0-1.2.rc15.el5.i386.rpm
cyrus-imapd-perl-2.3.7-1.1.el5.i386.rpm
cyrus-imapd-utils-2.3.7-1.1.el5.i386.rpm
db4-utils-4.3.29-9.fc6.i386.rpm
lm_sensors-2.10.0-3.1.i386.rpm / 对应 libsensors.so.3
cyrus-imapd-2.3.7-1.1.el5.i386.rpm
cyrus-sasl-2.1.22-4
cyrus-sasl-md5-2.1.22-4
cyrus-sasl-plain-2.1.22-4
cyrus-sasl-lib-2.1.22-4

现在遇到的问题是SMTP认证通过可以成功发送邮件(客户端FOXMAIL测试向163邮箱发送成功且163邮件可以正常接收)，IMAP/POPS认证似乎也通过了
[root@localhost tmp]# telnet localhost 110
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
+OK localhost.localdomain Cyrus POP3 v2.3.7-Invoca-RPM-2.3.7-1.1.el5 server ready <[e-mail]>
user postfix

但163邮箱向我的POSTFIX邮件服务器发送可能成功发出，但我确收不到邮件内容，通过查看/var/log/maillog日志总是有一个这样的错误日志：

我的[root@localhost tmp]# cat /etc/imapd.conf 配置信息如下：
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

tls_key_file: /etc/pki/cyrus-imapd/cyrus-imapd.pem
tls_ca_file: /etc/pki/tls/certs/ca-bundle.crt

我的 /etc/cyrus.conf 部分配置信息如下：
SERVICES {
  # add or remove based on preferences
  imap          cmd="imapd" listen="imap" prefork=0           //这里原来是5我改为0了
  imaps         cmd="imapd -s" listen="imaps" prefork=1
  pop3          cmd="pop3d" listen="pop3" prefork=0         //这里原来是3我改为0了
  pop3s         cmd="pop3d -s" listen="pop3s" prefork=1
  sieve         cmd="timsieved" listen="sieve" prefork=0
....
}

求教各位高手，谢谢!!!
