102 Kaspersky Anti-Spam 2.0 Enterprise Edition / ISP Edition
If the program has been installed using the standard setup options, kas-pipe will
be used for integration with the Postfix and the Exim mail systems.
kas-pipe receives mail via SMTP/LMTP protocols using its standard receiving
facility and returns the filtered messages via SMTP/LMTP/pipe.
kas-pipe is started by an external application (MTA or inetd), the mail is
transferred either via a network (or a local) socket or by means of mail receiving
application fork+exec launched for this purpose.
The diagram of modules interaction during Kaspersky Anti-Spam operation using
kas-pipe is presented below:
