Why does Mail app contact iCloud when sending a non-iCloud email?
When sending an email from a non-iCloud account in macOS Mail app, the app unexpectedly triggers connections to iCloud's gateway even when iCloud Mail is fully disabled in System Settings. The cloudd and nsurlsessiond processes attempt to reach CloudKit API endpoints for querying and saving records. Certificate pinning prevents traffic inspection via Proxyman, and network extensions don't expose unencrypted data either, leaving the reason for these connections unknown. The author has resorted to blocking these connections via Little Snitch rules as a workaround.
