Please note that ITL, as many other companies, use commercial Mail Service Provider (MSP) for its email hosting. This means that all email messages are traversing through a 3rd party mail server unencrypted (even if SSL/TLS is used to transfer messages between servers). The MSP thus has, by definition, unrestricted access to any unencrypted email message send to/from ITL. This means that all unencrypted email messages should be treated as if read by 3rd parties. Please use encryption when sending sensitive information to ITL (see our PGP key below). ITL cannot be held responsible for any potential leak of information that have been sent to ITL via unencrypted email.

The PGP key for email encryption can be found here.
