I recently heard about a postman who got suspended for telling customers how to reduce the amount of junk mail they get. The post office make a fortune from delivering this rubbish and its hardly environmentally friendly.

I did a search and found these tips for reducing junk mail, cold calls from telesales during dinner etc.:

Post - Mailing Preference Service - http://www.mpsonline.org.uk - 0845 703 4599 "Can take up to four months for mail to stop. ... removes your name from up to 95% of junk mail lists. Will not stop mail from overseas, unaddressed mail, mail addressed to "the Occupier", or mail from small local companies."
