GFI – Fighting Against NDR Spam
Spamming has become one of the costliest misbehaviors of internet for last few years. When spamming gets together with marketing, it creates a huge impact on the well-being of the internet. There are number of measurements that have been taken for stopping spamming but it looks like spammers find more sophisticated techniques day-by-day which helps them to continue on what they do.
NDR Spam (Non Delivery Report Spam) is one of the common forms of spamming which would result from usual spamming. Let’s try to understand more of NDR spamming. A spammer can send spam emails to thousands and sometimes, millions of email users by using your email address (as sender). You may wonder how they do that without having access to your email account. It’s quite simple; when emails are sent through SMTP, senders email address is not authenticated for existence or validity. So, anyone can mention someone else’s email address when they send emails even though it is not legitimate. Out of those thousands or millions target emails addresses of spam, there are so many email addresses that are not valid or do not exist. Whenever an email is sent to an invalid email address, a NDR will be sent back to the sender. In this case, since your email has been used as the sender for spamming, you will end up getting thousands of NDRs. This is what we call NDR spam or backscatter spam.
