Hello All,
We have a website host on a server and there is a high availability between 2 servers (website servers). programming team are deploying a new application and that application must sends notification to their emails ( External Mails hotmail , ... etc). When they are trying to send test email, they got an error 5.7.1 unable to relay. Our exchange server is 2013, should i configure IIS on website server for SMTP and exclude those IPs, or should be done through exchange server ( creating a new receive connector ). If tired to create a new receive connector and then i check TLS then run :
Get-ReceiveConnector "SMTP Relay" | Add-ADPermission -User 'NT AUTHORITYAnonymous Logon' -ExtendedRights MS-Exch-SMTP-Accept-Any-Recipient
Then i got an error "NT Authority not found", if i remove TLS checkbox then restart the server, its working fine. I did it on my LAP
Best Regards,
