如何將註冊郵件退回到 noreply@ 郵件地址
在 CentOS 7 Linux 上，我執行 Drupal，它要求使用者確認他們的郵件地址。
我通過以下方式修改了後綴配置文件：
/etc/後綴/通用：
@www.localdomain noreply@preferans.de/etc/postfix/main.cf:
smtp_generic_maps = hash:/etc/postfix/generic這導致 Drupal 向新使用者發送註冊郵件，其中包含以下標題：
From: noreply@preferans.de <--- non-existing address at my domain Reply-To: First.Last@gmail.com <--- my private mail address這很好用（比以前更好，當我設置
From:為我的 Gmail 地址並且 Gmail 認為我的網站正在向其他人發送垃圾郵件時），但我有一個問題：我不想再接受任何發給任何人的郵件
@preferans.de（太多垃圾郵件湧入），所以我刪除了伺服器 DNS 條目中的 MX 記錄，並通過 iptables 關閉了埠 25。現在當一個新的 Drupal 使用者輸入一個虛假地址時，註冊郵件會退回，
noreply@preferans.de但我的 postfix 安裝無法傳遞它：/var/log/maillog：

如何配置我的 postfix 安裝，以便它立即刪除未發送的郵件（但仍然通過灰名單）？
最後是目前的postconf -n輸出：
alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix data_directory = /var/lib/postfix 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 html_directory = no inet_interfaces = localhost inet_protocols = all mail_owner = postfix mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man mydestination = $myhostname, localhost.$mydomain, localhost newaliases_path = /usr/bin/newaliases.postfix queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.10.1/README_FILES sample_directory = /usr/share/doc/postfix-2.10.1/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop smtp_generic_maps = hash:/etc/postfix/generic unknown_local_recipient_reject_code = 550
我的解決方案是設置
bounce_queue_lifetime = 2d在/etc/postfix/main.cf中將退回郵件的生命週期縮短到 2 天
