I once worked for an organization where I learned of a "feature" with SMTP servers, which can allow for unbounded replication of a single email. Without giving out too many of the details, if the organization has both internal and external SMTP servers, a properly formatted email can replicate out of control. The trick was to play the two servers against one another by creating an email with multiple recipients all of which are within the same organization but are undeliverable. Each time the email is returned and forwarded it will be replicated. 2,4,8,16,32,.. you get the idea? I believe that Pipex stumbled across this same "feature" by indiscriminately sending to addresses that were scoured off the web. I wonder where I should put my latest email addresses on the web so Pipex can find it?;->
