Send but cannot receive
We check MX records, domain routing, mailbox existence, provider status and whether another server is still claiming local delivery.
Email Troubleshooting
Business email not working? Start with the failure, not the guess.
If business email can send but not receive, receive but not send, bounce or suddenly stop working, the cause is usually traceable through DNS, provider routing, authentication, mailbox configuration or account state. DSDillon works from the symptom back to the failing layer.
Why it matters
How this affects your business
01
Inbound inquiries may be lost.
02
Outbound messages may bounce or fail silently.
03
Temporary fixes can mask the root cause and fail again.
Business Email Health Check
Check your domain’s email setup.
Enter your domain to check its public email records. The results show what we found and what needs a closer look. This check cannot confirm inbox placement. You do not need to enter an email address.
Receive but cannot send
We check SMTP authentication, provider restrictions, SPF/DKIM configuration, account security and whether the sending path matches the intended provider.
Stopped after a DNS change
Website, email and verification records can coexist, but one careless zone edit can redirect or invalidate a service. We compare the current DNS zone against the intended mail architecture.
