why would the firewall administrator accept mail traffic tunneled over
HTTP any more than mail traffic sent over port 587? I would hope that
network usage policy is not tied to physical port numbers, but rather on
an analysis of information leakage threat and similar.

this trend to use port 80 for everything is not making anything more
secure. it just means firewall hardware needs to be more and more beefy
in order to do advanced content parsing to distinguish plain browsing
from bad traffic.
