Abstract

Messages having a reputation score higher than at least one message already on a queue are added to the queue when the queue has already reached the predetermined maximum permitted size. One or more messages having a low reputation score may be discarded from a bottom of the queue in favor of a new incoming message having a higher reputation score. This may be particularly useful in the context of Internet e-mail, wherein mail delivery protocols (i.e. SMTP) allow a connection for an incoming message to be held open for a limited time period and during this period the message processing apparatus does not assume responsibility for onward transmission of the message. Thus, the message processing apparatus is able to selectively accept only those messages having a highest reputation score for detailed analysis, without adversely affecting the operations performed by other parts of the electronic messaging system.
