Good luck.  Prof. Knuth stopped reading email years before there was a
big spam problem.  He uses his own version of hashcash to cut down on
unimportant mail: if you want to write to him, you have to send him
snail mail, which means buying and using an actual postage stamp.

I do something like that, sort of.  I no longer publish an email
address, including on business cards and so forth.  I have a contact
url that I give out instead, which keeps me off mailing lists.
