Postfix 從本地使用者發送郵件，但不從 mailman

我正在嘗試為本地俱樂部設置 Mailman 伺服器，但遇到了 Postfix 和 Mailman 的奇怪問題。我認為問題出在 Postfix 上。

所以問題是我可以通過 mail 命令從本地使用者發送郵件，但是當我嘗試從 mailman 發送郵件時我沒有收到郵件。

以下是 /var/log/maillog 中已發送且我能夠接收的電子郵件的範例：

May  1 20:15:18 vps-1152677-20287 postfix/qmgr[16785]: ED274AA901B1: removed

以下是我未收到的郵遞員發送的電子郵件範例：

May  1 20:14:50 vps-1152677-20287 postfix/smtpd[16889]: connect from localhost[127.0.0.1]

我猜它與來自本地主機的連接有關，但是我認為我在後綴配置中已經涵蓋了這一點。

這是我用於 Postfix 的 main.cf：

queue_directory = /var/spool/postfix
command_directory = /usr/sbin
daemon_directory = /usr/libexec/postfix
data_directory = /var/lib/postfix
mail_owner = postfix
myhostname = mail.akblacksmith.club
mydomain = akblacksmith.club
myorigin = akblacksmith.club
inet_interfaces = all
inet_protocols = ipv4
mydestination = mail.akblacksmith.club, akblacksmith.club, localhost.akblacksmith.club, localhost, localhost.localdomain
unknown_local_recipient_reject_code = 550
mynetworks = 127.0.0.0/8
relay_domains = $mydestination
relayhost =
alias_maps = hash:/etc/aliases, hash:/etc/mailman/aliases
alias_database = hash:/etc/aliases
recipient_delimiter = +
debug_peer_level = 2
debugger_command =
    PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin
    ddd $daemon_directory/$process_name $process_id & sleep 5
sendmail_path = /usr/sbin/sendmail.postfix
newaliases_path = /usr/bin/newaliases.postfix
mailq_path = /usr/bin/mailq.postfix
setgid_group = postdrop
html_directory = no
manpage_directory = /usr/share/man
sample_directory = /usr/share/doc/postfix-2.6.6/samples
readme_directory = /usr/share/doc/postfix-2.6.6/README_FILES

我不太清楚為什麼後綴會發送一條消息而不發送另一條消息。

謝謝您的幫助

事實證明，Gmail 的印像是郵遞員的電子郵件是垃圾郵件……
