Lawful Interception in the world...

I'm trying to collect some informations on Lawfull Interception over the world... Does any country in the world require such things ? LOGS (6 months archive required) - mail header logs (all mails, in, out, relay) - pop3/imap/webmail access logs (all accounts) - dhcp/dial/adsl/gprs/whatever accounting logs (all users) RealTime - mail interception (IN,OUT,RELAY) for a certain From/To address or a certain IP. the mail has to be encrypted with PGP and sent directly to the Law enforcement as a mail attachement. Thank you for taking 2 minutes to answer to nanog or privatly, this is important. P.
