Hi All,
We currently have a few domains that are experiencing high levels of email spoofing. They are receiving emails from what appear to be internal email addresses.
I am aware there is a fix with the powershell command:
Get-ReceiveConnector “My Internet Receive Connector” | Get-ADPermission -user “NT AUTHORITY\Anonymous Logon” | where {$_.ExtendedRights -like “ms-exch-smtp-accept-authoritative-domain-sender”} | Remove-ADPermission
But I wanted to check, this should only effect the external receive connector meaning if i have set up another anonymous connector for internal functions like scan to email and such that only accept emails from specific internal IP addresses then this shouldn't effect anything from those connectors
I would just like to clarify exactly what type of traffic will this block.
