What does the error code ‘571 Delivery not authorised message rejected’ mean?

We’ll look at what this problem implies and how to repair it today. The 571 error is caused by problems with the recipient mail server, and it typically occurs when the recipient mail server stops messages from the sender mail server. Email error 571 means that the sender is not allowed to send to the recipient. This could be because of server-wide or domain-specific blocks. This is a Microsoft Exchange server-specific error message. The bounced mail will contain the error 571 for the sender whose letter was rejected.

Email blocking can occur for a variety of reasons:

1. The receiving server has blacklisted the sender’s IP address

To prevent spam from accessing their server, many receiver servers utilise specialised spam blocking software like Spamfilter or Antivirus. Firewalls are used on certain servers to prevent questionable IP addresses. If the sender’s mail server is marked as a spam source by these tools, mail from that sender is blocked and the error message “571 delivery not authorized, message refused” is shown.

2. The sender’s IP address lacks RNDS

Many destination servers look for reverse pointers to verify the sender’s legitimacy. An RDNS allows you to confirm that the sender is legitimate and trustworthy. Because of this RDNS security restriction, servers that receive emails from senders who don’t use RDNS may reject them and send them back with the error message “571”. “Delivery is not permitted, and the message is denied.”

3. Spamhaus and other spam-filtering services have banned the sender

Some mail servers check server reputations on spam lists like Spamhaus and ban servers with bad IP reputations. As a result, if the sender is banned from Spamhaus, the recipient’s mail server may refuse messages from that sender.

4. Email filters that are specific to the receiver’s domain

In addition to server-wide email filters and blocks, each domain on a server can have its own set of bespoke email filters. Even if there are no restrictions on the server as a whole, an email might be rejected because of filters, blacklists, or security rules that are specific to the recipient.

5. The sender’s mail server’s blocks or filters

While error 571 is most commonly caused by recipient mail server blockages or rejections, it can also be caused by the sender mail server in some instances. Outgoing firewalls or antivirus software are configured on certain systems to limit traffic sent from them to specific destinations. Email delivery issues can also be caused by these barriers or filters. The letter would be rejected if the sender address was an external one that was not authorised to send mail to a distribution list.
