Appendix A 111
Two techniques are used to avoid infinite looping:
• kas-cgpro adds a special header to each message it has processed and
later checks messages for such headers;
• by default kas-cgpro processes only those messages that were
received using SMTP protocol (see the AllTransports configuration
parameter).
A.3.6.2. The
kas-cgpro configuration file
The kas-cgpro program's operation parameters are specified in configuration file
/usr/local/ap-mailfilter/etc/kas-cgpro.conf.
