Probe a host to see if it looks like an Exchange Autodiscover endpoint. |
- thunderbird_accounts.mail.autodiscover_probe.exchange_autodiscover_endpoint_exists(hostname: str, domain_name: str) bool[source]
Probe a host to see if it looks like an Exchange Autodiscover endpoint.
Resolve the DNS name to confirm it’s public IP, not private. To avoid a race condition with resolving the domain a second time, we re-use the IP in the connection string and send the DNS name in the host header.
After allowing AUTODISCOVER_PROBE_MAX_REDIRECTS, we check the headers for an Exchange-like header.
Finally, we’ll check to see if the response body looks like Exchange.
