GNU Mailman3 + Postfix：550 5.1.1 <root@localhost>：收件人地址被拒絕：本地收件人表中的使用者未知

我只是想用 Postfix+Nginx+Postgres 執行 GNU Mailman3。這是最新的 GNU/Linux Debian 穩定版，所以我剛剛apt-get安裝mailman3-full並對配置文件進行了一些標準更改。Nginx 部分很好，SSL 工作正常，我可以從我的網路瀏覽器訪問 Postorius 和 Hyperkitty。但是當嘗試以管理員身份登錄時，我收到以下錯誤：

在 Postfix 日誌文件中：

Feb 25 21:39:55 vps-xxx postfix/smtpd[122820]: connect from localhost[::1]
Feb 25 21:39:55 vps-xxx postfix/smtpd[122820]: NOQUEUE: reject: RCPT from localhost[::1]: 550 5.1.1 <root@localhost>: Recipient address rejected: User unknown in local recipient table; from=<root@MYDOMAIN> to=<root@localhost> proto=ESMTP helo=<vps-xxx>
Feb 25 21:39:55 vps-xxx postfix/smtpd[122820]: disconnect from localhost[::1] ehlo=1 mail=1 rcpt=0/1 rset=1 quit=1 commands=4/5

我想：也許我的本地收件人表不知何故壞了？但我可以使用以下方式發送郵件mail：

$ mail -r 'root@localhost' -s 'just a test' 'root@localhost'

它工作得很好：

Feb 25 21:44:12 vps-xxx postfix/pickup[124104]: 9ABB540516: uid=1000 from=<root@localhost>
Feb 25 21:44:12 vps-xxx postfix/cleanup[124763]: 9ABB540516: message-id=<20220225214412.9ABB540516@MYDOMAIN>

Feb 25 21:44:12 vps-xxx postfix/qmgr[118558]: 9ABB540516: removed

我root確實可以在 ’s Maildir 中看到它。

有任何想法嗎？

如果我沒記錯root@localhost的話，是我admin在dpkg-reconfigure. 我以前從未使用過 GNU Mailman3，但我猜這封電子郵件一定是登錄通知或類似的東西（您也可以通過send_email_confirmation函式名稱猜測它）。如果我輸入了錯誤的密碼，一切都很好（我只是在 Web UI 中得到一個很好的錯誤），所以只有當密碼正確時才會發生這種情況。

謝謝！

問題是在GNU Mailman 文件中它說：

要配置 Postfix，請將以下配置添加到 main.cf：

# 支持預設的VERP分隔符。
收件人分隔符 = +
unknown_local_recipient_reject_code = 550
owner_request_special = 否
運輸地圖 =
雜湊：/path-to-mailman/var/data/postfix_lmtp
local_recipient_maps =
雜湊：/path-to-mailman/var/data/postfix_lmtp
中繼域=
hash:/path-to-mailman/var/data/postfix_domains

這就是我所做的。但是，我沒有意識到的是，此配置有效地禁用了/etc/aliases文件，甚至禁用了本地傳送到rootor root@localhost。修復者：

local_recipient_maps =
代理：unix:passwd.byname $alias_maps 雜湊：/var/lib/mailman3/data/postfix_lmtp
