As email delivery is critical to most organizations that do business online, ensuring the integrity and reliability of their mail exchanger (MX) servers and their corresponding records is of utmost importance. But why is that so?
Well, MX records identify the mail servers responsible for receiving incoming emails and determining the recipients of outgoing ones. An incorrectly routed MX record, therefore, can cause problems with email delivery because of a mismatch in the sender’s details, which could lead the email to be marked as spam or blocked. This can definitely affect a company’s internal and external communications, particularly its marketing efforts.
