Abstract: A system comprising email processing circuitry, web server circuitry, third-party interface circuitry, and a database, wherein the database stores information about a plurality of users. The system receives, via a network, a first email message and generates a modified first email message by insertion of a link to remotely-hosted content in the received email message. The system transmits, via a network interface, the modified first email message. The system receives, via a network, a request for the remotely-hosted content, and updates the database based on information contained in the request for the remotely-hosted content. The system receives, via a network, information about activity on a third-party system, and updates the database based on the information about activity on the third-party system. The system receives a second email message, determines an action to take on the second email message based on information in the database, and takes the action.

Abstract: A system comprises circuitry configured to operate as a calendar synchronization service and to operate as a database service. The calendar synchronization service is configured to query the domain name system to determine which one or more levels of event information are permitted to be propagated from a first electronic calendar hosted by a first calendar host to a second electronic calendar hosted by a second calendar host. The database service is configured to store rules for propagating events on the first electronic calendar to the second electronic calendar. The calendar synchronization service may be configured to receive, via an application programming interface (API), a notification of a first event on the first electronic calendar, wherein the first event has a start time, duration, summary, description, and one or more attendees. The calendar synchronization service is configured to determine, based on the rules, to-be-propagated other properties of the first event.

Abstract: In accordance with an example implementation of this disclosure, an email processor comprises mailbox management circuitry and replacement email message generation circuitry. The mailbox management circuitry is operable to configure an email message filtering rule for an email mailbox such that email messages that meet criteria specified in the email message filtering rule: bypass an inbox of the email mailbox, and are assigned a first metadata value specified in the email message filtering rule. The mailbox management circuitry is operable to fetch, from the email mailbox, an original email message to which the first metadata value has been assigned. The replacement email message generation circuitry is operable to generate a replacement message for the original email message.

Abstract: A system which hosts an electronic forum comprises memory in which is stored profiles of users of the electronic forum, memory in which is stored posts of the electronic forum, and notification generation circuitry. The notification generation circuitry is operable to, automatically in response to creation of a post to the electronic forum, inspect the post for an occurrence of a particular tag. The notification generation circuit is operable to determine, automatically in response to a detection that the post contains an occurrence of the particular tag, which of the users are both subscribed to the particular tag and have permission to view the post; and send, automatically in response to a determination that a first one or more of the users are both subscribed to the particular tag and have permission to view the post, a notification of the post to the first one or more of the users.

Abstract: A custom email handler comprises network interface circuitry and in-line email processing circuitry. The network interface circuitry uses the simple mail transfer protocol (SMTP) to receive an email message that has already visited a sender's mail transfer agent (MTA). The in-line email processing circuitry searches a subject header field and/or a message body of the email message for a character string matching any of a predefined set of custom email processing commands. In response to one of the predefined set of custom email processing commands being found during the searching, the in-line email processing circuitry modifies the message body in accordance with one or more rules associated with the found command, and removes the found command from the subject header field and/or the message body. After the modifying and the removing, the email is sent, via the networking interface circuitry, into a network destined for a recipient's mail transfer agent.
