Mailman 無法將電子郵件中繼到非本地域

我的電子郵件伺服器在虛擬域設置中執行帶有 postfix、dovecot、amavis、mailman 和 postfixadmin 的 Debian。一切正常，除了郵遞員無法將電子郵件中繼到非本地域（“中繼訪問被拒絕”），而我可以將電子郵件中繼到任何具有後綴身份驗證的 smtp 的收件人。

下面是我的設置。

日誌中的錯誤：

May 11 09:06:42 gabble postfix/smtpd[8390]: NOQUEUE: reject: RCPT from www.my-domain.it[127.0.0.1]: 554 5.7.1 <user@external-domain.com>: Relay access denied; from=<mylist-bounces@lists.my-domain.it> to=<user@external-domain.com> proto=ESMTP helo=<gabble.my-domain.it>

提前感謝您提供的任何幫助。

該relay_domains參數確定 Postfix 中繼到哪些域- 即您的電子郵件伺服器除了其郵件名之外還將接受郵件的域 - 所以這行在這裡不會幫助你（我假設這是你正在嘗試的無論如何，要實現它）。

您將 MAIL FROM 地址限制為中列出的地址/etc/postfix/access- 確保包括lists.my-domain.it.

根據 postconf(5) 的說法，您的生產線相當早，除非兩者reject_unauth_destination之一smtpd_recipient_restrictions

• 解析的 RCPT TO 域匹配 $relay_domains 或其子域，或
• Postfix 是最終目的地：已解析的 RCPT TO 域匹配 $ mydestination, $ inet_interfaces, $ proxy_interfaces, $ virtual_alias_domains 或 $virtual_mailbox_domains

如果您希望此框能夠發送它生成的任何郵件，您需要添加permit_mynetworksbefore reject_unauth_destination，以便來自您網路的郵件無論發送到哪裡都會被批准。
