Then what is the point of having an outside mail server?
If it can be breached, and you let your external mail server
connect to the internal mail server that has exactly the
same vulnerabilities as the external one.... (....
time for the previous to sink in ..... )
Uhmmmm...
Of course, the matter is another one if the firewall
in question has a real store-and-forward SMTP proxy.
Does it do this?
If it doesn't, you might aswell consider your internal
mail server to be directly accessible from the Internet,
since it is only a matter of first cracking the external
one before slamming away at the internal one.
