Due to enormous spam (for 10 users 7.000.000 messages in 230 days). I`m implementing Anti-Spam to block recipients who are not in the global address list.
I used the solution presented by sembee in this post:
After doing so i recieved this error in the eventlog: "Anti-spam agents are enabled, but the list of internal SMTP servers is empty. If there are any MTAs between this server and the Internet, populate this list by using the Set-TransportConfig cmdlet in the Exchange Management Shell. " Event id: 1022
As this is the only exchange server (and smtp server) in the domein i gave the commando set-transportconfig -InternalSMTPserver localhostipadres
The problem is that the anti-spam doenst block anything.
