Postfix 5.7.1无法中继

我有以下情况：

• serverA =使用Sendmail的RHEL5
• serverB =使用Postfix的RHEL6
• serverC =使用Postfix的RHEL6
• gwsmtp = relayhost
• example.com =域名

当我们从sendmail迁移到postfix时，我们会遇到一些无法转发错误的情况。

详细解释一下：

• 从serverA到serverB，我可以发送没有问题的电子邮件
• 从serverA到serverC，我可以发送没有问题的电子邮件
• 从serverB到ServerA我无法发送电子邮件
• 从serverB到serverC我无法发送电子邮件

从serverB发送电子邮件到serverA我得到以下反弹消息

• Postfix消息ID始发进程？
• 后缀：发件人依赖中继和主机的邮件
• 垃圾邮件 – 个人用户
• 后缀分割域使用LDAP分隔邮件存储
• iptables +后缀无法发送电子邮件

我在serverB上使用了以下main.cfconfiguration

 mydomain = example.com myhostname = serverB myorigin = $myhostname inet_interfaces = all mydestination = $myhostname, localhost.$mydomain, localhost, $myhostname.$mydomain, hpmedtsa, hpmedtsa.$mydomain relayhost = gwsmtp.$mydomain queue_directory = /var/spool/postfix command_directory = /usr/sbin daemon_directory = /usr/libexec/postfix data_directory = /var/lib/postfix mail_owner = postfix inet_protocols = all alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases debug_peer_level = 2 debugger_command = PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin ddd $daemon_directory/$process_name $process_id & sleep 5 sendmail_path = /usr/sbin/sendmail.postfix newaliases_path = /usr/bin/newaliases.postfix mailq_path = /usr/bin/mailq.postfix setgid_group = postdrop html_directory = no manpage_directory = /usr/share/man sample_directory = /usr/share/doc/postfix-2.6.6/samples readme_directory = /usr/share/doc/postfix-2.6.6/README_FILES transport_maps = hash:/etc/postfix/transport 

这是我们在serverA上的sendmail makro

我们尝试在sendmail中使用与postfix相同的configuration。 任何帮助将不胜感激。
