The issue is the increasingly high percentage of internet connections which are

inability of the folks in Redmond to deliver non-broken software such that a large
enough fraction of portable machines are able to "credential hijack" from stored
credentials on the machine and impersonate the operator while botted.

I really don't get it. While I understand with tcp/25 blocking, there is absolutely no reason to block tcp/587. If credential's are being hijacked, it is the responsiblity of the MSA server to close the door. There's nothing to say those credentials weren't blasted to an irc server or a web script somewhere and the actual usage of them will be from some other random location on the net.
