Postfix 5.7.1 无法中继

Postfix 5.7.1 无法中继

我有以下情况：

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

当我们从 sendmail 迁移到 postfix 时，我们遇到一些无法中继的错误。

详细解释一下：

  • 我可以毫无问题地从服务器A向服务器B发送电子邮件
  • 我可以毫无问题地从服务器A向服务器C发送电子邮件
  • 我无法从服务器B向服务器A发送电子邮件
  • 我无法从服务器B向服务器C发送电子邮件

从服务器 B 发送电子邮件到服务器 A，我收到以下退回消息

我在 serverB 上使用以下 main.cf 配置

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 serverA 上的 sendmail makro

我们尝试在 postfix 中使用与 sendmail 相同的配置。如有任何帮助，我们将不胜感激。

您应该将 sendmail 的“直接向同一域中的其他主机发送”技巧迁移到 postfix。[您报告了在两种配置中都使用了智能主机]

发送邮件

发送邮件

LOCAL_NET_CONFIG
R$* < @ $* .$m. > $*    $#smtp $@ $2.$m. $: $1 < @ $2.$m. > $3

后缀

主配置文件

transport_maps = hash:/etc/postfix/transport

/etc/postfix/transport (需要编译postmap /etc/postfix/transport)

my.domain    :
