Hit Microsoft hard and fast with a major leaflet campaign?

We have port 25 open. Given that this is an authenticated service it
shouldn't pose a security risk really.

The problem really kicks in when people are sending via ISPs which block, or
transparently proxy, port 25. Then Outlook users are screwed from a security
point of view (forgive me for stating the obvious) because they just can't
use TLS no matter what.

If I had the time I'd be looking at testing Outlook, SSL and stunnel on
other ports because I believe that Outlook can manage that.
