I received a suspicious email that appeared to come from my account via Mailgun after DNS forwarding was reconfigured. How can I address this spoofing issue?
hey, check up on your spf and dkim setting after the dns change. maybe some old mailgun settings are still active allowing spoofers. updating those records correctly might help
I faced a similar situation during a recent migration. I discovered that lingering Mailgun references in my DNS were the main issue. After switching to Squarespace, not all old records were updated, and that left an opening for spoofing. My resolution was to completely clean up my old DNS entries and ensure that SPF, DKIM, and DMARC configurations were set up anew according to the updated service provider’s guidelines. This method not only improved overall security but also stopped any unauthorized emails from being sent under my domain.
