Email is a complicated process and interpreting the exact meaning of a bounced email can be challenging. Different servers process messages differently. One of the hardest things to do is determine what the message is telling you to do. Mail servers sometimes split the message between the body of the bounce message and an attachment. ResponseMaster has the most accurate bounce email processor in the industry. The state-of-the-art software breaks the bounced email into 18 parts. Once the email has been broken into parts, the program applies sophisticated rules to determine the type of bounced message. It can differentiate between different types of bad email addresses.
