How Telegram Enforces Inbound Message Permissions Server-Side

Under MTProto, message permissions are evaluated at edge proxy servers before dialogs can be created:

filter_alt

inputPrivacyKeyChatInvite & SendMessage: When a user invokes messages.sendMessage to a new peer, the server queries the recipient's privacy rule list. If the sender is neither a mutual contact nor Premium, the RPC terminates with a PRIVACY_PREMIUM_NORMAL_USER error.

chat_bubble

Zero Dialog Creation: Unauthorized messages are blocked before reaching your phone. No empty chat bubble is created, no notification sounds, and zero battery or memory is wasted on spam.

handshake

Outbound Handshake Exemption: When you send a message to a non-contact, Telegram generates a temporary bidirectional communication lease, allowing them to reply to your specific dialog.
