Hello im trying to configure my exchange 2016 server so it dont get BACKSCATTER
Ive done this on my server
Set-Remotedomain default -NDREnabled $true
Set-RecipientFilterConfig -RecipientValidationEnabled $true
and restart Transport Service
Now when im sending an email from gmail to an invalid email address firstname.lastname@example.org ive got a reply from

The mail system

RESOLVER.ADR.RecipientNotFound; Recipient not found by SMTP address lookup
(in reply to end of DATA command)
Is this a normal behavior ?
Should i not receive an email from GMAIl instead to notify me that the adress firstname.lastname@example.org don't exist
Thanks for helping me
