Mailshell Gateway Installation
First you need to install the RPM as root.
This example assumes that you are installing version 1.2
release 2 of the Mailshell Gateway RPM. Please substitute
the appropriate RPM version as necessary.
1) su root
2) rpm -i spamcatcher-1.2-2.i386.rpm
Configuration
The main configuration file is here: /etc/spamcatcher/conf/spamcatcher.conf
Before the Mailshell Gateway is started,
it is advisable to configure at least four settings.
1) listen_port -
This specifies the port that the Gateway will listen to
for incoming connections. Default is 25 if not specified.
2) outgoing_server -
This specifies the destination SMTP server that the Gateway
will forward packets to. Default is localhost if not specified.
If you would like to specify more than one
server, you can list them on this line, separated by commas.
The listed servers are used in a round robin fashion.
3) outgoing_port -
This specifies the port that the Gateway will forward packets
to on the destination SMTP server. Default is localhost
if not specified.
Starting and Stopping
the Mailshell Gateway
To start, you can run the following command
/etc/rc.d/init/spamcatcher start
To stop, you can run the following command
/etc/rc.d/init/spamcatcher stop
Evaluation Tips
Mailshell Gateway tags each processed message
with a header called "X-SpamCatcher-Score" signifying its
spam score. The range is from 0 to 100. The higher the score
the more likely the message is spam.
Tips on Setting Up SMTP
Server
Note: If the Mailshell SMTP Gateway
is on the same internal network as the Mail Transfer Agent,
it is possible that the MTA will act as an open relay for
unwanted messages. You can prevent this from happening by
configuring your MTA to disallow open relaying of messages
for the IP address associated with the SMTP Gateway.
