Chapter 5. NOD32LMS configuration
verify = false
This section has to be placed as first section among all ROUTER CONFIGURATIONS sections.
In case of Exim 4 it is only necessary to comment out the line
domains = +local_domains
from already existing ’nod32_router’ ROUTERS CONFIGURATIONS section defined by rules
in section 5.2.2.6. of this manual.
To accomplish the whole procedure, one has to restart both the MTA Exim.
5.5. Alternative methods of scanning e-mails.
Although mechanisms described in previous sections are concerned to be the basic mechanisms
of the e-mail messages scanning, there exists yet other possibilities that are all described in this
section.
5.5.1. Scanning e-mail messages using AMaViS
AMaViS - A Mail Virus Scanner is a tool that interfaces your MTA and several antivirus scanners.
It supports Sendmail, qmail, Postfix, Exim and comes in three branches:
amavis
for low/medium mail volume
amavisd
for higher mail volume, daemonized version of amavis
amavisd-new
for higher mail volume, Anti-Spam, ISP features, ...
Amavis cooperates with NOD32LMS by using its command line interface nod32cli (see the
nod32cli manual page for details). Yet before we go into detailed explanation of the Amavis -
NOD32LMS configurations, we would like to discuss the impact of the method on the
NOD32LMS software functionality.
First, one should note that Amavis does not allow modification of the body of scanned e-mail
messages directly by NOD32LMS software. Particularly, no infected e-mail message processed
and delivered to the final recipient will be cleaned directly by NOD32LMS software. Another
consequence is that no NOD32 footnote will be written into the e-mail body.
Another feature of the described method is that the modification of e-mail header is indirect
from the point of view of NOD32LMS software. Particularly, status dependent, header modifi-
cation directly by NOD32LMS is disabled.
