machines either not listening on port 25 or have the primary MX
firewall drop connections to port 25, if you want to check that your
secondary works. There are of course other variations. But the best
method would be to set up the secondary initially protected from
incoming port 25 connections except from some test host. You can then
test your secondary by connecting manually to port 25 from another
host (NOT in the relay_from_host list).

the error from the log would help here. But I wonder if you had the
primary MX pointing at some private address.
