was not delivered due to an authentication issue. Specifically, the email did not pass the Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) authentication checks, which are used to verify that the email is coming from a legitimate source and not a spammer.

The error message also indicates that the SPF check for the domain texascustomcreditrepair.com did not pass with the IP address 66.96.188.3, which may be the IP address of the server that sent the email. This suggests that there may be an issue with the domain's DNS records, which can be checked and corrected by the domain owner or administrator.

To resolve this issue, you can try sending the email again after ensuring that your email authentication settings are correct, including your SPF and DKIM records. You may also want to contact the recipient and let them know that their email server has blocked the message, and ask if there is an alternate email address or another way to contact them.
