US Patent 7613778 Progressive de-featuring of electronic messages

Provided is a messaging system capable of detecting and processing at least a portion of a malformed message, e.g., a message that previously failed to process. An identifier and state information for the message can be logged. Based on the stored information, a determination can be made that the message previously failed to process. The message can then progressively be de-featured until the message can be processed or until the message is determined to be poisonous, whereupon it can be deleted or otherwise removed from the message stream permanently or temporarily—including moving the message to storage for operator inspection or for delayed delivery.
