请问exchange可以拦截无寄件者的信件吗?

请问这是一种退信攻击吗?exchange server 2019该如何去拦截无寄件者的信件?

设一条规则寄件者=<>，仍然拦截不到

请问有好方法吗?谢谢!

使用PowerShell建立规则

New-TransportRule -Name "Is Empty Mail" -Condition @( New-TransportRulePredicate -SenderAddressMatchesPatterns "^$" )
-Action @(
New-TransportRuleAction -RejectMessageReasonText "Empty sender addresses are not allowed."
)
