But what do you do when you address is myaddr@mydomain.com and spammers send you mail at myaddrdd@mydomain.com? Well make up a fake MTA and pick it up and see what they wanted.
The most shameless spam I got this way had a "confidentiality" notice attached to it which read:
No part of this newsletter mayAnd the spam was even copyrighted!
be reproduced in any form or by
any means, electronic or
mechanical, including
photocopying, recording or via
any other information storage
and retrieval system, without
our written permission.
Cool! You have to admire their gumption.
