Dear Members,
I've problem with the following situation:
- there is a Hyper-V 2012 host, containing two VM's:
-- one for antivirus and antispam solution
-- one for Exchange 2013 CU3 installed
- the internet connection goes through a firewall, the incoming SMTP traffic is forwarded to the antivirus host
- the antivirus host is sending (relaying) the checked traffic to the Exchange host
- the Exchange is deferring all messages, in the log: TransportRoles\Logs\FrontEnd\ProtocolLog\SmtpReceive can be found:

I created a new Receive Connector like this:
Permission group: Anonymous
Remote network system: the IP of antivirus system
Network adapter bindings: All IPv4, Port 25
From [PS]:
Get-ReceiveConnector “Receive Connector Name” | Add-ADPermission -User “NT AUTHORITY\ANONYMOUS LOGON” -ExtendedRights “Ms-Exch-SMTP-Accept-Any-Recipient”
Any ideas?
Best Regards,
