Understand NDR Attacks Before You Waste Time & Money
An email is created and sent to a fictitious address using your domain. Using the forged sender e-mail address, they make it appear that the email is coming from the intended spam recipient.
Because the email is from an unknown sender, your email server cannot deliver the spam. In this way, a non-delivery report (NDR) is generated and returned to the sender. The sender address, however, has been forged by the spammer, as a result, the non-delivery notification goes to another recipient.
Your server is now relaying spam to an innocent victim on behalf of a spammer since non-delivery notifications often include the content of the original email.
The malware landscape is a constantly changing one, and NDR is one of the best defenses against it. Hence you must protect your network security. Here are three things that you need to remember:
A network security solution cannot guarantee 100% protection against malware
Since a constantly growing signature database is challenging to maintain
The wrong solution can result in false positives, wasting valuable time and money

Look for an email security software that has all these key features:
Junk filtering
End-to-end encryption
Archive messages
Prevent IP Leakage
Email Compliance
