Hi Andy
Am I right to assume that if port 25 is firewalled from the outside then
the risk from external hacks is minimal?
Cheers

Hi,
Most hosts, unless they are acting as a server listed in one or more
domains' MX records, do not need to be remotely accessible on port
25. If that's the case for you then you would be well advised to
reconfigure Exim to only listen on localhost. Though there are still
11 other vulnerabilities that local users could exploit. At least
you'd only get rooted by a friend, right?
