問題
我一直在 virtualbox 中配置虛擬郵箱進行測試，但是它似乎接受所有用戶，甚至是 virtual_mailbox_maps 中未定義的用戶，儘管清除了 mydestination （因此它不會作為本地郵件處理）並添加一些 smtpd_recipient_restrictions
當我測試將郵件發送到不存在的郵箱（但退出網域）時，例如
echo "This is the body of the email" | mail -s "This is the subject line" [email protected]
/var/log/maillog 顯示
postfix/qmgr[14474]: E890D1883308: from=<[email protected]>, size=470, nrcpt=1 (queue active)
E890D1883308: to=<[email protected]>, relay=myhook, delay=0.6, delays=0.03/0.01/0/0.56, dsn=2.0.0, status=sent (delivered via myhook service)
這意味著它被接受並發送到虛擬傳輸而沒有拒絕。
希望得到一些幫助

答案1
問題是這個配置行
smtpd_recipient_restrictions = reject_unknown_recipient_domain reject_unauth_destination reject_unverified_recipient
您必須檢查限制中的收件人地址。查看check_recipient_access配置參數：
smtpd_recipient_restrictions =
reject_unknown_recipient_domain,
reject_unauth_destination,
reject_unverified_recipient,
check_recipient_access mysql:/etc/postfix/mysql-virtual-mailbox-maps.cf
