I like this :-)
By sending an email message to any address that will cause it to end up in my mailbox you hereby agree that:
- I am by definition “the intended recipient” of the message;
- you either make no intellectual property claims to the message or grant me a royalty-free, perpetual, irrevocable, non-exclusive and fully sublicensable right to use, reproduce, modify, adapt, publish, ridicule, create derivative works from and distribute the content.
This overrides any disclaimer or statement of confidentiality that may be included in your message. Since it is trivial to intercept, read, modify and forge email messages and by design email messages are relayed and distributed by multiple entities any statements embedded in an email messages regarding confidentiality or legal validity of statements in non-encrypted email are silly.
