在後綴爲防止這可怎麼辦：
smtpd_recipient_restrictions = [...]
permit_sasl_authenticated,
check_sender_access proxy:mysql:/etc/postfix/mysql/mysql_virtual_nosasl.cf,
[...]
的第一條規則從誰通過了SASL讓用戶的電子郵件。第二個檢查是否在MAIL FROM中的發件人域是我的域之一。如果是這樣，它將阻止來自554的電子郵件。檢查規則* _限制在第一場比賽結束。因此，如果來自我的域的發件人尚未完成permit_sasl_authenticated，則意味着它不是我的用戶，並且應阻止另一個規則。
DirectAdmin exim.conf如何做到這一點？
