Jan 11 14:51:55 mail postfix/smtpd[20559]: NOQUEUE: reject: RCPT from hanghau.pacific.net.hk[202.64.33.147]: 554 5.7.1 <zhang_san@man.mtcera.com>: Sender address rejected: Access denied; from=<zhang_san@man.mtcera.com> to=<myname@mtcera.com> proto=ESMTP helo=<hanghau.pacific.net.hk>



这是我的一个域内的成员在局域网发邮件给我，怎么HELO成了别人的服务器，
不解，求大家帮助！

谢谢

[root@mail ~]# postconf -n local_recipient_maps
[root@mail ~]#


下面是我的关于发信的MAIL.CF 配置信息，能否看出什么问题：
smtpd_banner = $myhostname ESMTP $mail_name
smtpd_error_sleep_time = 0s
smtpd_recipient_restrictions = permit_mynetworks,reject_sender_login_mismatch,permit_sasl_authenticated,reject_non_fqdn_hostname,reject_non_fqdn_sender,reject_non_fqdn_recipient,reject_unauth_destination,reject_unauth_pipelining,reject_invalid_hostname,check_policy_service inet:127.0.0.1:10030
smtpd_restriction_classes = local_only
smtpd_sasl_auth_enable = yes
smtpd_sasl_local_domain = $myhostname
smtpd_sasl_security_options = noanonymous
smtpd_sender_login_maps = hash:/etc/postfix/sender_login_maps
smtpd_sender_restrictions = check_recipient_access hash:/etc/postfix/local_recipient check_sender_access hash:/etc/postfix/sender
unknown_local_recipient_reject_code = 450
virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf
virtual_mailbox_domains = mysql:/etc/postfix/mysql_virtual_domains_maps.cf
virtual_mailbox_maps = mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf
