And filtering 445 in the outbound direction to prevent attacks from the inside

Unfortunatly I've ran into at least 1 rather big example of a company
using 445 for SSL since they wanted to put more then 1 cert on a machine.

In this case it was a check clearing house, and a bank couldn't reach them
because their ISP was filtering their T1.
