• 🔍 Smart Autodiscover SCP: Sets AD SCP to your trusted domain or clears it ($null) for Office 365 / EXO Relay setups.
• ✉️ Send Connector: Creates an outbound Internet Send Connector (SMTP:*, DNS routing) if missing (-CreateSendConnector).
• 📦 Message Limits: Sets global send/receive limits across Transport and all connectors in one shot (-MaxMessageSize "50MB").
