Occasionally I hear people talk about mail-enabled lists, and I've read a
doc or two about setting them up, but here's the sixty-four thousand dollar
question: how do you secure the whole process?
Anybody can send an email. Lots of people know how to spoof the "from"
headers. Any sort of hash or key sent in the message is subject to
interception; this is why we have an emerging secure email market. However,
secure email appears less than convenient at this juncture; is it a viable
solution? Is SPF the answer? Am I making any sense?
Feel free to respond to this with anything resembling constructive
criticism.
