除特定收件人外，我无法将电子邮件发送给某个域中的任何人。 以下是我在隔离/caching日志中看到Maia（隔离程序）向用户发送的新邮件的电子邮件：

我的服务器主机名为emmxgw0（.mailtest.mycompany.com），但该DNS条目实际上并未在我的DNS服务器中定义（此时使用8.8.8.8）。 我的main.cf是：
myhostname = emmxgw0.mailtest.mycompany.com alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases myorigin = mailtest.mycompany.com mydestination = mailtest.mycompany.com relayhost = mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 mailbox_size_limit = 0 recipient_delimiter = inet_interfaces = all mydomain = mailtest.mycompany.com local_transport = error:no local mail delivery local_recipient_maps = virtual_alias_maps = hash:/etc/postfix/virtual relay_domains = mailtest.mycompany.com smtpd_helo_required = yes smtpd_data_restrictions = reject_unauth_pipelining smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination transport_maps = hash:/etc/postfix/transport content_filter = smtp-amavis:[127.0.0.1]:10024
和我的运输文件是
mailtest.mycompany.com relay:[10.5.1.10]
我应该提到，工作的用户jshin与Linux服务器上存在的用户帐户名称相同，所以也许这就是为什么它正在工作？
当日志格式化了一点之后，你现在可以很容易地看到这个循环包含3个继电器，4个IP地址和3个不同的MTA，并且按照这个顺序依次循环：
该transports文件解释了为什么Postfix将邮件从127.0.0.1closures到Microsoft SMTP服务器，而content_filter行解释了为什么Postfix将邮件从其他地方邮件发送到Maiad，但是我们无法理解另外两个邮件传递查看Maia和Microsoft SMTP服务器的configuration。
是Postfix还是应该将邮件传递给收件人的SMTP服务器的Microsoft SMTP服务器？
