Email Domain Health Check
Could a scammer send emails pretending to be your business? This checks the three DNS records that decide — SPF, DMARC and MX — and explains what they mean like a human.
Enter just the part after the @ — e.g. fentech.ie. The lookup goes to Google's public DNS service; nothing is stored.
Records missing or confusing?
SPF, DKIM and DMARC set up properly is part of every Fentech Microsoft 365 job — one visit and your domain stops being spoofable.
