Using a virtualmin cloud mail filtering provider

[dynaweb.net]

We would like to use virtualmin as a mail server for clients who receive a lot of spam and scams. Unfortunately, too many come through with the provided mail virtualmin filtering. There is very little information online about the ‘Cloud mail filtering provider’ options available in virtualmin. Recommendations before we begin our testing would be highly appreciated. Thank you beautiful Virtualmin community

My advice would be to look into Postscreen:
Postfix has this wonderful feature called Postscreen. https://www.postfix.org/POSTSCREEN_README.html

It would deter a majority of spammers that attack your postfix email servers.
