86 Kaspersky Anti-Spam 3.0
• ClientDefaultDomain – the mail domain name set-up to addresses which
have no mail domain specified. Example: if you specify the domain
mycompany.com as the default mail domain, then the address someuser
will be interpreted as [e-mail]. If you did not define
this parameter, then the domain name substitution is not performed (by
default this parameter is not defined).
• ClientFilteringSizeLimit – maximum message size (in kilobytes) that can
be passed to the filtering server. The e-mail messages of a greater size
are allowed to pass without processing by filtering server. The default
value is: 500.
• ClientMessageStoreMem – minimum message size (in kilobytes), at
which storing temporary data on disk is allowed. This mode allows
controlling the amount of used RAM. To store all data in RAM, set this
parameter to 0 (the default value).
• ClientTempDir – path to the temporary files storage directory.
A.2.3. kas-milter – a client module for the
Sendmail mail server
For integration with Sendmail mail server, Kaspersky Anti-Spam uses the kas-
milter module. Interaction of the client module with the mail server is done by
means of the libmilter library.
The Figure 31 illustrates the modules interaction scheme when Kaspersky Anti-
Spam is used with Sendmail.
Figure 31. Interaction of Kaspersky Anti-Spam with the Sendmail mail server
Configuration of interaction between a client module and mail server can be
performed either using special scripts (see item 3.5 on page 27), or manually.
Manual configuration of the client module is done by editing the filter.conf
configuration file located in the /usr/local/ap-mailfilter3/etc/ directory. The
following is a fragment of this file containing the client module settings:
ClientConnectTo tcp:127.0.0.1:2277
ClientConnectTimeout 10
ClientDataTimeout 30
SendMailAddress unix:/var/run/kas-milter.socket
