Install Simscan
Simscan is a C program that allows the administrator to do virus, spam, and attachment scanning at the SMTP level. It is still very much under development, and often the best features are only available via CVS.
rootshell> useradd -u 320 -c "SimScan Daemon" simscan
shell> cvs -d :pserver:anonymous@chicago.inter7.com:/home/cvs checkout simscan
shell> cd simscan
shell> ./configure --enable-spam --enable-clamav --enable-per-domain --enable-spam-hits=100 --enable-spamc-user --enable-received --disable-ripmime --enable-spamc-args='-U /tmp/spamd.sock'
The configuration options above are defined as follows :
--enable-spam
Turn on spam scanning
--enable-clamav
Turn on clamav scanning
--enable-per-domain
Turn on per domain based checking
--enable-spam-hits=number
Reject spam above this hit level
--enable-spamc-user
Set user option to spamc
--enable-received
Add a Received: line to the message, showing the scanners run and some stats
--disable-ripmime
Disable ripmime program
--enable-spamc-args=ARGS
Override the default spamc arguments
Some quick notes. Setting the spam-hits option is not strictly necessary since we are enabling per-domain settings. However, this will allow for an upper default limit for all domains. The spamc arguments I specify above use a local socket connection rather than a tcp connection.
shell> make
rootshell> make install
Simscan installation is now complete. There is still a bit of configuration to be done. See the below configuration section for more information.
