Causes and Solutions for Xfinity Error Code 554
Now that we've identified the concept, let's look at how to fix "554 permanent problems with the Xfinity remote server."
Cause: Sender IP Blacklisted
- The reason for this is that the sender's IP address has been blacklisted.
The sender's IP address has a poor reputation, which is the main cause of that error. It's likely that the sender's IP address has been blocked or blacklisted for spamming and open relays.
- Most security systems, such as SpamHaus, DNSSBL, SORBS, and others, can block the mail server IP in such situations.
- Xfinity services verify the reputation of an IP address before allowing a connection, and it will not be allowed to send emails.

The first step in resolving the problem is to ensure that the sender's IP address does not have a poor reputation. As a result, the server must be protected and outgoing spam must be controlled. The best option is to disable POP and SMTP.
Cause 2: The sender was marked as spam.
Most users use filters and blacklists to keep spam at bay. Filters and blacklists set very strict guidelines for managing incoming junk mail, and they sometimes block messages that contain banned elements. The recipient's guidelines must be followed by all senders; otherwise, the emails will not be sent. For example, a message containing spam words will be restricted by the remote server because it was suspicious. Furthermore, Xfinity does not permit the sending of bulk emails since the email sending limit must be conformed to. The 554 error will occur in such circumstances.
Before sending a post, it's important to assess its nature. As a consequence, file formats, spam content, and unwanted content should all be disabled before submitting the file.
It's also crucial to ensure that your domain or IP is whitelisted on the list of recipients in order to keep the work flow going.
Cause 3: Insufficient DNS Records
Another explanation the sender is rejecting your emails may be due to a bad DNS record for the sender's domain. RDNS (PTR), SPF, and DKIM are the most common variables used by the recipient server to verify the sender's identity.
To resolve issues relating to bad DNS records, make the necessary changes to the records as soon as possible. Third-party services can be used to retrieve the PTR, SPF, DKIM, DMARC, and other DNS records.
