Regarding mail you're not strictly correct. Military computers, utilising Microsoft's latest 1997 technology, offer many features that cause e-mail not to reach destination, often
without an error message. Address books list addresses that nobody apparently ever logs onto and fairly regular unexpected denials of service from servers/networks/drives.
Even if the system is working, a moronic system of file naming created by FoI clouds the ability to find anything and the plods' contribution - having to type 'Internet-Authorised:' in the title of every off-base e-mail - is a valuable
tool to preventing people efficiently just pressing 'send'.
JPA follows a proud history of the military screwing around with technology that seemed to work okay for everyone else.
