I've done work for a certain bank in Minnesota that actually had business customers
email their ACH deposit files (plain text) to a Hotmail.com address, where they downloaded
it from, and processed it without question (uh, hello?). At one point a company I worked
for was actually using them for ACH deposits, and were told that we would have to bring
the ACH file on a floppy disk because hotmail claimed that the email had a virus attached.

oh yeah, every computer in the building had a modem, connected to a POTS line, waiting to be 
dialed into.

Maybe burying money in mason jars is safer..
