All versions of Exim previous to version 4.89.1 are now obsolete.
The Exim team recommends to upgrade to the latest version. The last 3.x release was 3.36. It is obsolete and should not be used.
With Rapid7 live dashboards, I have a clear view of all the assets on my network, which ones can be exploited, and what I need to do in order to reduce the risk in my environment in real-time. No other tool gives us that kind of value and insight.
