Method for the filtering of messages in a communication network

A communication network comprising:

• at least one messaging server and at least one wireless node;
• a first filtering entity in said at least one messaging server configured to store first filtering criteria, to determine whether a first message is spam, and to determine second filtering criteria based on said first filtering criteria and a feedback message;
• a messaging entity in said at least one messaging server configured to receive said first message, to provide information on said first message to said at least one wireless node and to receive the feedback message from said at least one wireless node;
• and
• a messaging client in said at least one wireless node configured to retrieve information on said first message from said messaging entity, to allow a user to determine whether said first message is spam, and to provide said feedback message to said messaging entity.

A computer program embodied on a computer readable medium comprising code configured to perform the following steps when executed on a data-processing system:

• storing first filtering criteria in a messaging server;
• receiving a first message in said messaging server;
• determining whether said first message passes said first filtering criteria in said messaging server;
• providing information on said first message to a wireless node;
• receiving a feedback message identifying said first message to said messaging server;
• and
• determining second filtering criteria based on said first filtering criteria and said feedback message.

A communication network, comprising:

• storing means for storing first filtering criteria in at least one messaging server;
• receiving means for receiving a first message in said at least one messaging server;
• determining means for determining whether said first message passes said first filtering criteria in said at least one messaging server;
• retrieving means for retrieving information on said first message to at least one wireless node;
• allowing means for allowing a user to determine whether said first message is spam;
• providing means for providing a feedback message identifying said first message to said at least one messaging server;
• and
• determining means for determining second filtering criteria based on said first filtering criteria and said feedback message.
