後綴：“中繼訪問被拒絕”
我一直在關注本教程： http: //flurdy.com/docs/postfix/index.html
出於某種原因，即使在確保我正確設置它之後，它也不會向外部域發送任何郵件。它仍然可以從他們那裡接收，但發送結果如下：
postfix/smtpd[26338]: NOQUEUE: reject: RCPT from localhost[127.0.0.1]: 554 5.7.1 <xxxx@gmail.com>: Relay access denied; from=<user@domain.com> to=<xxxx@gmail.com> proto=ESMTP helo=<domain.com>我已經啟用了 TLS，還有 amavis。禁用任何一個（或兩者）都不會改變任何東西。我也可以發送到我自己的域，它會正確到達。
這是我的 /etc/postfix/main.cf：

reject_unauth_destination從中刪除smtpd_client_restrictions。編輯
