When configuring Mailgun on WHM, I encounter issues with the TXT record for SPF. I set it as: v=spf1 include:postmasterapi.net ~all, but without quotes it truncates, causing Mailgun not to recognize it. How can I fix this?
I encountered a similar issue when setting up Mailgun with WHM. The problem turned out to be with how WHM handles TXT records by default. I manually edited the DNS zone file and added the SPF record with quotes to ensure it was completely recognized. This approach prevented the truncation issue. I also made sure to flush the DNS cache after updating the record to see the changes. The manual edit bypassed WHM’s default limitations, which resolved the issue without compromising Mailgun’s requirements.
Based on my experience, the issue might be related to how WHM interprets the TXT record without proper encapsulation, leading to an inadvertent truncation of the record. Rather than relying solely on the WHM interface, it’s advisable to directly modify the DNS zone files. This allows for customized insertion of the SPF record using the proper quoting mechanism. In my case, manual editing and subsequently clearing the DNS cache yielded consistent results. Additionally, verifying the DNS propagation via external tools proved valuable in confirming that Mailgun received the complete record.
