我在 Postfix 上有以下 header_checks
/^Received:/ IGNORE
/^X-Originating-IP:/ IGNORE
/^X-Mailer:/ IGNORE
/Message-Id:\s+<(.*?)@www.mainserver.com>/ REPLACE Message-Id: <$1@www.domain.com>
/X-Mailer-LID:/ IGNORE
/^MIME-Version:/i PREPEND Precedence: bulk
/X-Mailer-RecptId:/ IGNORE
/X-Mailer-SID:/ IGNORE
/X-Mailer-Sent-By:/ IGNORE
/List-Unsubscribe:/ IGNORE
一旦我在postfix/main.cf（运行后postmap /etc/postfix/header_checks）激活它们，postfix 就会停止工作。当我尝试发送电子邮件时，我收到以下错误日志
