A messaging system receives a message that is intended for a recipient, who is a user of a social networking system. An object associated with the message is identified based on the message content and/or metadata associated with the message. The messaging system accesses a social networking system database to obtain social information about a relationship between the recipient and the identified object. The message is then indexed using the social information, wherein an entry for the message is stored in a message index based on the social information. This process may be repeated for each received message, and multiple different message indexes may be generated for received messages to track different types of social information. A user interface for viewing messages uses the message index to organize the messages, such as to filter, categorize, and/or sort the messages in the display.

Organizing messages in a messaging system using social network information

The disclosed techniques provide systems and methods for deletion of end-user messages, message threads, attachments, and/or other message information. More specifically, a key-value store residing in computer memory on the storage system is described. Each value in the key-value store is indexed by a key and structured to include multiple column portions associated with multiple column families. In one embodiment, a deletion column family having an associated retention policy for data stored therein is defined.

Message and attachment deletion

A messaging system that organizes and presents messages to users of the messaging system. The messaging system includes a mailbox module that receives messages and generates conversation threads from the messages. Messages received from different electronic message channels may be aggregated into a common conversation thread. The conversation threads are also organized in a message interface and then presented to a user of the messaging system. The messaging system may include a social networking system that stores social information about users, which can be used to organize the conversation threads. Other features include a multi mode message interface, and a method for adding contextual information to messages.
