Hello, Did you just send a message to `%(recipient_address)s`?

No?  Please ignore this.  Someone has misused your email address.

Yes? Then verify your intent by replying to the present message
     at its default `Reply-To` address.  To do this:

   * Either use the ordinary *reply* function of your mail client;

   * Or, send your reply (any content, or just an empty message) to
     `%(confirm_accept_address)s`.

Sorry for the inconvenience, but your email address is unfamiliar.
Therefore your message is held and will not be delivered unless you
reply to this challenge within %(pending_lifetime)s.
