## Abstract

A method, system and apparatus for selectively blocking the transmission of an unsolicited instant message. The method of the invention can include receiving an instant message designated an intended recipient; locating the intended recipient in a do not instant message list; and, responsive to the location, blocking the instant message for subsequent transmission to the intended recipient. Notably, the blocking step can include the step of selectively blocking the instant message based upon a specified policy defined for the intended recipient.

## Claims

### Claim 1

A method for selectively blocking the transmission of an unsolicited instant message, the method comprising the steps of:
receiving for routing to an instant messaging client, an instant message in an instant messaging server managing instant messaging communications between instant messaging clients over a computer communications network, the instant message designating an intended recipient;
locating said intended recipient in a do not instant message list in the instant messaging server; and,
responsive to said location of said intended recipient in said do not instant message list, blocking routing of said instant message for completion of transmission of said instant message to said intended recipient by determining whether said instant message is an unsolicited instant message transmitted from a bot and selectively blocking said instant message if said do not instant message list indicates that unsolicited instant messages are to be blocked, and requiring sender of the instant message update a local copy of the do not instant message list so as to incorporate the designated recipient in the local copy.

### Claim 2 (depends on 1)

The method of claim 1, wherein said blocking step comprises the step of selectively blocking said instant message based upon a specified policy defined for said intended recipient.

### Claim 3 (depends on 1)

The method of claim 1, wherein said blocking step comprises the step of selectively blocking said instant message based upon a specified policy defined for said intended recipient and for content in said instant message.

### Claim 4 (depends on 1)

The method of claim 1, wherein said blocking step comprises the step of performing selective blocking selected from the group consisting of absolutely blocking said instant message, queuing said instant message for later delivery and redirecting said instant message.

### Claim 5 (depends on 1)

The method of claim 1, wherein said blocking step further comprises the step of transmitting an updated local copy of said do not instant message list to a source of said instant message.

### Claim 6 (depends on 5)

The method of claim 5, further comprising the step of logging said transmission for said source of said instant message.
