I would like to create an application, which well be inserted between the mail client (outlook express, or mozilla, etc) and a remote pop3 server. It is something like email scanners do. I want control the mail data. (actually it will be special a spam filter). I have searched google, but could not find any information, how to integrate an applicaton with the TCP data flow. I need only the basic concept.
Any help would be appriciated.
Thanx, have a nice day,
