FOR UNWANTED PAPER MAIL or first class junk mail:

Bulk mail is the hardest to deal with because the Postal Service actively provides addresses, support and encouragement to mailers. So, here’s what you do. If "address correction requested" is written on the label, circle it and treat it like first class junk mail.For catalogs, you can either call the company’s 800 number and have the label handy, or write your desired instructions on the catolog’s mailing label and fax it to the company.

If you have a mailto link on your page, expect to get junk mail. You can remove the mailto link and force people to manually enter your email address. This will cut down spam considerably.

Further, you can state your email address in a way readable only to humans (e.g. bryce at machine uclink.berkeley.EDU).For Newsgroup postings, you can use an obviously false return address on all postings. Most news programs let you set your return address as whatever you’d like. Include your real email address in the body of your posted message.
