publishing at least one of the email addresses, the published email address being an address that is utilized to determine when an email addressed to the user is a valid email from a legitimate sender; and
when an email is received by the user addressed to the True address, automatically checking the second address for receipt of a matching email to determine whether the email received at the True address is a valid email;

Abstract
A match and destroy (MaDe) technique for filtering spam mail assigns at least two email addresses per user when the user first registers for an email account or when the MaDe software is installed on the server. The first email address is designated as the “True address,” and the user is made aware of only this address. The second email address is designated as the “Trap address,” and the user is not made aware of this address. Spammers send spam mail to all available email addresses as a spammer is unable to differentiate a True address from a Trap address. A MaDe filter is provided that detects when the same email is received in both the True and the Trap(s) inboxes. When this duplicate receipt occurs, the filter informs the resident spam filters that the email is a spam candidate.
