How urgent is this?

What's happening? Include your version, provider (M365 / SES / etc.), and any error from the Queue's lastError if you have it. Please describe the issue so we can help.

We'll reach out on the contact method(s) you provided. Critical mail-flow-down issues are prioritized first.

📚 Check the docs first

The documentation covers the most common issues — stuck queues, auth failures, port conflicts, and certificate warnings — with step-by-step fixes.

🗂 Grab your logs

If the service is misbehaving, the wrapper log and relay.log under %ProgramData%\SmtpRelay\logs are the fastest path to a diagnosis — mention what you see there.

💡 Not broken, just missing?

If it's something SMTP Hopper doesn't do yet, tell us on the feature request page — we read every single one.
