I have my prefered method as well. I use a form based mail facility for people making the intital contact.

The form is precssed server-side and an email sent to the designated recipient.

Only the server-side code knows the actual email address. The originator of the email only ever finds out what the persons email address was if they choose to reply to that initial contact.

I could be wrong but I think this method is the ultimate spambot proof.
