Chapter 5. NOD32LMS configuration
Note: Please, in case you are reading the ASCII form of this guide, do not drag and drop the
above sentence, since it may not work. Indeed, it can be that the switches used here as an exam-
ple will not work in your case as they are dependent on the version of Sendmail MTA.
With the above modifications we have ensured that all the messages originally sent by the MTA
for delivery to the MAILBOX (by using an original MDA) will now be primarily sent to module
nod32mda. Yet remains the second part of the modification to provide that all messages pro-
cessed by nod32mda will be sent to the original MDA. In order to do so, we have to modify
the parameter ’mda_path’ within the section [mda] of the main NOD32LMS configuration file
(/etc/nod32/nod32.cfg) to the original MDA component. The original MDA component can
be, at this stage of the procedure, still found in the back-up file (/etc/mail/sendmail.cf.orig)
you have created. Thus assuming your original MDA component is (/usr/bin/procmail) the
appropriate parameter of the main NOD32LMS configuration file will look like this:
mda_path = "/usr/bin/procmail"
To accomplish the whole procedure, one has to restart both the MTA Sendmail and the daemon
nod32d.
5.2.2.2. Setting Postfix MTA
An MTA Postfix stores its configuration in several files. However, the modifications necessary
to be described in this section will be done only with the main Postfix configuration
file (/etc/postfix/main.cf) and of course with the main NOD32LMS configuration file
(/etc/nod32/nod32.cfg).
First one has to grab information on the MDA used by Postfix. This can be found by explor-
ing the main Postfix configuration file (/etc/postfix/main.cf). To make all things easier, the
authors of Postfix have written a helper utility to work with this file, so called ’postconf’, so
all the necessary steps will be done by using this utility. Also, before any further steps, please
make a back-up of the original main Postfix configuration file (for instance, with the name
/etc/postfix/main.cf.orig).
Now let’s assume that the original MDA component is ’/usr/bin/maildrop’. Then by using a
command
postconf mailbox_command
we will receive the following information on return:
mailbox_command = maildrop -d "$USER" "$EXTENSION"
In the next step we will use the ’which’ command
which maildrop
