ESET Mail Security
A.1. Setting
ESETS
for MTA Postfix
A.1.1. Inbound email message scanning
Warning
:
This installation is not compatible with SELinux. Either disable SELinux or
proceed
to
the next section.
The objective of this installation is to insert
esets_mda
before the original Postfix MDA. The
MDA to be used (with arguments) is set in the Postfix parameter ‘mailbox_command’.
NOTE:
If the ‘mailbox_command‘ value is empty, Postfix alone is delivering mail . You must install and
configure a real MDA (e.g. procmail) and use that first for the ‘mailbox_command’ and arguments
(e.g. /usr/bin/procmail -d “$USER”). Reload Postfix and make sure it is delivering mail according to
your needs. You may then continue with the ESETS installation.
Take the full path to the current Postfix MDA and set the parameter ‘mda_path’ in the [mda]
section of the ESETS configuration file to:
mda_path = ”/usr/bin/procmail”
Restart the ESETS daemon. Then, replace the path to the current Postfix MDA with
esets_
mda
path and add -- --recipient=”$RECIPIENT” --sender=”$SENDER” to the arguments, as in the
following example:
mailbox_command =
@BINDIR@
/esets_mda -d ”$USER”
-- --recipient=”$RECIPIENT” --sender=”$SENDER”
To re-read the newly created configuration, reload Postfix.
A.1.2. Bi-directional email message scanning
The objective of this installation is to divert all mail from Postfix to
esets_smtp
and get
them back to Postfix. In the [smtp] section of the ESETS configuration file, set the following
parameters:
agent_enabled = yes
listen_addr = ”localhost”
listen_port = 2526
server_addr = ”localhost”
server_port = 2525
Restart the ESETS daemon;
esets_smtp
will be started and will scan all SMTP communication
accepted on ‘listen_addr:listen_port’ and forward it to ‘server_addr:server_port’. To divert all mail
to
esets_smtp
set the following in Postfix:
content_filter = smtp:[127.0.0.1]:2526
NOTE:
If the ‘content_filter’ parameter already has a value, do not follow these instructions. Instead,
you must insert esets_smtp (or other ESETS mail scanning module) before or after your current
‘content_filter’.
