Bounce Back & Backscatter Spam: Who Stole My Email Address?

Tuesday, September 24th, 2013

spamSo, you’re minding your own business, going about your daily tasks, checking your email, and suddenly your INBOX is flooded with a series of non-delivery reports (aka NDRs or bounce messages).

VERP now supported for High Volume Bounce Analysis

Monday, February 28th, 2011

LuxSci’s High Volume Outbound Email service now supports the optional use of VERP / Variable Envelope Return Path for simplified bounce message analysis.

Normally, when an email message is sent, but fails to reach its destination, a “bounce message” is sent back to the “Envelope Sender” (i.e. the “Return path” address, which may or may not be the same as the “From” address).  These bounces inform senders of delivery issues and allow for the management and pruning of mailing lists.  However, there is no uniformity in the format of these bounces messages.  It is even sometimes the case that it is not possible to tell to whom the message was originally sent!  This makes analysis of bounces both difficult (no standard format) and imperfect (can’t always tell).

With this method of sending, the address to which bounces messages are sent (the Return Path) is customized for every recipient, so that it contains the failed address.
