Tracking SPAMmers

Your host is identified as clientid=x4hgq3nvo5jz.
The identifier, represented in 12 digits with BASE32 encoding, consists of the encrypted address of your host (7 digits) with the time stamp (5 digits).

Thus a mail sent to the address like <x4hgq3nvo5jz.trap@delegate.org> will be able to be used to detect when and who collected the address. So DO NOT send a mail to the address, if you are not a naive SPAMmer :).
