What is Email Autodiscovery?

Email autodiscovery allows email clients to automatically configure server settings. This check analyzes multiple autodiscovery methods:

Microsoft Autodiscover - DNS records (autodiscover.domain.com, SRV), Exchange V1 XML, Office 365 V2 JSON
Mozilla Autoconfig - Thunderbird-style autoconfig.domain.com and .well-known endpoints
RFC 6186 SRV Records - Standard mail service discovery (_imaps._tcp, _submission._tcp, etc.)
Security - Open redirect vulnerabilities that can leak credentials
