One way of trying to block spam is have any mailto link on a web page set up to
be " My name <webmaster@127.0.0.1> " as this IP address is reserved for "the
machine being sent from" or "mymachine" (depending how you look at it). another
possibility is to substitute postmaster instead of webmaster, or have links to
both. You will need to have an explanatory note on another address which will
not be picked up on a bot automatically trawling for addresses.
