我有一个邮件服务器（mail.mydomain.com），其中设置了一个中继：
/etc/postfix/main.cf ：
# Smarthost relayhost = [smtpcorp.com]:2525 smtp_sasl_password_maps = hash:/etc/postfix/smtpcorp_passwd 因此，我的任何使用mail.mydomain.com作为SMTP服务器的用户，基本上都会使用自己的用户名和密码进行身份validation（与dovecot使用的用户名和密码相同），然后他们会转到smtpcorp.com ，该用户名/密码是他们从未见过的。 这很好。
但是，当mail.mydomain.com运行cron脚本并尝试发送别名到我的电子邮件地址的根目录时，它将失败，因为没有进行身份validation。
Jul 27 08:34:06 mail postfix/smtp[5058]: D37641FA98: to=<[email protected]>, relay=smtpcorp.com[207.58.147.66]:2525, delay=0.96, delays=0/0/0.86/0.1, dsn=5.0.0, status=bounced (host smtpcorp.com[207.58.147.66] said: 550 Relay denied for unauthenticated sender (in reply to RCPT TO command))
我如何免除localhost和mail.mydomain.com ：
/ etc / aliases ：
mailer-daemon: postmaster postmaster: root root: [email protected]
如果我删除根别名，邮件传递工作正常，但我希望在那里的别名，以便它将转发和交付，所以我的常规邮件客户端可以通过dovecot访问它。
服务器信息：Debian 7.5，后缀2.9.6

您可以通过在transport_maps设置空继电器主机来将[email protected]排除为使用relayhost
