Barracuda: SPF Failure Remediation
E-mail relies on a set of authentication processes that help email servers determine if a sender is authorized to send email for a sender's domain. SPF records are one step in this process, and it is used to clearly specify what email servers are utilized by an organization. When Barracuda shows that a message was blocked due to SPF failure, it is due to one of the below reasons:
- Misconfiguration of the SPF record
- Malicious Activity (example: a spoofed message being sent from a none-authorized server
- Non-Configuration of the SPF record
HPG IT cannot resolve issues that result in SPF records being blocked, only the Sender's Domain/Mail administrators have the ability to properly configure their SPF records. Generally, instructions are provided by the mail host for configuring SPF records. Please inform any sender's of messages with SPF failures that they should ask their Domain/Mail administrators to correct the issue from their end.
HPG IT will provide any additional information that the Domain/Mail administrators may ask for, and HPG IT will apply temporary workarounds if available. However, due to the nature of this issue, there is no permanent solution that HPG IT can apply.
