Microsoft announced that they deprecated the support for the SmartScreen Antispam content filters for Exchange Servers. This script uninstall the old and retired SmartScreen Antispam Agents from the local Exchange Server.
There are known issues with the SmartScreen AntiSpam content filters if you run Exchange 2016 on Windows Server 2016. So removing them might be always a good idea if you want to have a stable Exchange.
The Script removes the following AntiSpam Agents:
- Content Filter Agent
- Sender Id Agent
- Protocol Analysis Agent
Before running the script and remove the AntiSpam Agents listed above, you should consider a solid alternative solution. There are several good on Premises Solutions available, and there are even more Cloud Services, including Microsoft’s own Exchange Online Protection (EOP). This could be handy if you have Office 365, you just change/tweak the Mailflow and your Mailboxes are protected.
My favorite solution is a CentOS based Linux Box running Postfix, SpamAssassin and MIMEDefang. I use this together with some AntiVirus solutions to scan all inbound and Outbound mails. However, this is just my personal favorite because it’s very reliable and flexible, but I know that many prefer a all-in-one solution running on Windows. Again, there are a lot of great solutions out there!
