Knowledge Base & Operational DocumentationHow to Prevent DNS Changes From Disrupting Business Email
11/10/2026
A website DNS change can unintentionally replace mail records or nameserver authority needed by business email.
Checks to make
Record current MX, SPF, DKIM, DMARC, and nameserver values before the change. Identify the authoritative DNS provider, apply only intended edits, then validate records from external resolvers and send controlled test messages.
When to get help
DNS and email support can plan and verify record changes together. Informatix Systems can assess the symptoms, evidence, and next steps. Contact Informatix Systems to discuss this issue.
