ESET Mail Security for Debian - 32 bit 3.0.15 under Ubuntu Server 9.04

[grolon]

Hi all,
I'm working with a couple of customers integrating ESET Mail Security for Debian - 32 bit 3.0.15 under Ubuntu Server 9.04, using postfix.

Installation is normal as manual says.

My /etc/esets/esets.cfg looks like this.
root@mib:~# cat /etc/esets/esets.cfg | grep ^[^#]

[global]
syslog_facility = "syslog"
syslog_class = "error:warning:summ:summall:part:partall:info:debug"
action_av = "scan"
av_clean_mode = "standard"
action_av_infected = "discard"
action_av_notscanned = "discard"
action_av_deleted = "discard"
av_quarantine_enabled = yes
action_as = "accept"
action_as_spam = "discard"
action_as_notscanned = "discard"
av_update_period = 60
av_update_username = "EAV-00000000"
av_update_password = "mmmmmmmmm"
as_update_period = 60

[wwwi]
agent_enabled = yes
listen_addr = "0.0.0.0"
listen_port = 8443
username = "admin"
password = "admin"

Problem : Customers claim antispam is not working. Using www interface -> control -> statistics; i can see a lot of mails coming to mail server but none is marked as SPAM. What is wrong with configuration?.

I have read the manual http://www.eset-la.com/manuals/eset_mail_security_ES.pdf (spanish). So dont RTFM me please. In page 22 manual says something about "av_enabled (Anti-Virus Enabled)" and "as_enabled (Spam Detect Enabled)" parameters, but i cant find them in /etc/esets/esets.cfg. Are they necesary?

Aditional info, removed Amavi-new and spamassassin and using ESET Solution only.

There is no mention about an AntiSpam Module.

Any help?

Thanks in advance

This is a shame. There is no support from ESET to solve this problem.

Comming from unix/linux suppor for 15 years i can say this problem is solved using old school skills. Theres is NO documentation about this, no PDF downloaded from ESET sites will you you the answer. No forum could help.

Here it is.

In order to get antispam working under any linux distro you have to do this procedure in addition to official ESET manual of ESET Mail Security.

In /etc/esets/esets.cfg modify these parameters

# action_as = "accept" this is default. Does nothing. AntiSpam module is not working. Accept anything.
# action_as = "reject" Reject everything, nothing will be delivered to user.
# action_as = "discard" Discard everything, nothing will be delivered to user.

action_as = "scan"
# This is the only option to activate AntiSpam module.

action_as_spam = "accept", "defer", "discard", "reject" what do you want to do when spam is comming ?.

action_as_notscanned = "accept", "defer", "discard", "reject" what do you want to when objects could not be scanned by Anti-Spam scanner.

After changing theres parameters, fisrt update all modules; then restart.
NOTICE : you mail server could be out of service until update proccess is finished.

I run:
root@mib:~# date; /etc/init.d/esets_daemon restart; date
jue jun 18 15:25:04 PYT 2009
Restarting ESET Security for Linux: esets_daemon
Updating anti-virus modules...
Anti-virus modules update done(this is easy)

Start first time anti-spam modules update,
it may take several minutes, please wait...
error[582c0000]: Anti-spam modules update failure: Network error, disabling anti-spam.
.

root@mib:~#

I have included date command in order to know how long takes update proccess, official support said could not be more than 10 minutes, BTW this info is not docummented, but it took more than 35 minutes.

For some reasons you will not be adviced that an update proccess is taking place. If you can see a message like

error[582c0000]: [B][COLOR="Red"]Anti-spam modules update failure:[/COLOR][/B] Network error, disabling anti-spam.

Just repeat the procces and wait.

Or, you can update it manually:

root@mib:~# esets_update
Virus signature database has been updated successfully.
Installed virus signature database version 4180 (20090623).
root@mib:~#

Finally, you cand see your log if activated

Astispam module is updated.

Official support said this is documented under manpage. You tell me if you find it and why make it so difficult

root@mib:~# man esets.cfg

action_as = action

type: string

default: action = "accept"

Defines action to be performed on all e-mail messages approaching Anti-Spam control. Possible values are "scan", "accept", "defer", "discard",
"reject". Note that the values above are handled individually by every ESETS agent module. Thus to get description of the values please, refer to
section HANDLE OBJECT POLICY of manual page of an appropriate agent.

action_as_spam = action

type: string

default: action = "accept"

Specifies the action performed on e-mail messages found as spam. Possible values are "accept", "defer", "discard", "reject". Note that the values
above are handled individually by every ESETS agent module. Thus to get description of the values please, refer to section HANDLE OBJECT POLICY of
manual page of an appropriate agent.

action_as_notscanned = action

type: string

default: action = "accept"

Specifies the action performed on objects that could not be scanned by Anti-Spam scanner. Possible values are "accept", "defer", "discard",
"reject". Note that the values above are handled individually by every ESETS agent module. Thus to get description of the values please, refer to
section HANDLE OBJECT POLICY of manual page of an appropriate agent.

root@mib:~# man esets_mda

action_av_deleted, action_as, action_as_spam and action_as_notscanned. To get description of these configuration options, see esets.cfg(5) manual page.

action_av
|accept||scan||defer,discard,reject| -> object not accepted
| |
| action_av_infected
| action_av_notscanned
| action_av_deleted
| |accept||defer,discard,reject| -> object not accepted
| |
| action_as
| |accept||scan||defer,discard,reject| -> object not accepted
| | |
| | action_as_notscanned
| | |accept||defer,discard,reject| -> object not accepted
| | |
+-------+-------+
object accepted

Every e-mail message processed by this module is first handled with respect to the setting of the configuration option action_av. Once the option is set
to âacceptâ (resp. âdeferâ, âdiscardâ, ârejectâ) the object is accepted (resp. deferred, discarded, rejected). If the option is set to âscanâ the object
is scanned (resp. also cleaned if requested by configuration option av_clean_mode) for virus infiltrations and set of action configuration options
action_av_infected, action_av_notscanned and action_av_deleted is taken into account to evaluate further handling of the object. If action âacceptâ has
been taken as a result of the three above action options the object processed shall be scanned for spam.

Note that the e-mail message is scanned for spam only in case the configuration option action_as is set to âscanâ. In this case the action configuration
options action_as_spam and action_as_notscanned is taken into account. If action âacceptâ (resp. âdeferâ, âdiscardâ, ârejectâ) has been taken as a result
of the two above action options the object is accepted for further delivery (resp. the object is deferred, discarded or rejected).

You have probably noticed that each of the action configuration options discussed above accepts a variety of the values whose list can be found in
esets.cfg(5) manual page. As also stated there the values listed are handled individually by every ESETS agent module. Thus to be consistent in the folâ
lowing we review the meaning of the values for this ESETS agent module.

accept Accept object on this level of Handle Object Policy, i.e. access to the object is allowed by the particular action configuration option.

scan Scan object for virus infiltrations (resp. for spam) and clean infected objects if requested by configuration option av_clean_mode.

defer Return temporary failure to sender.

discard
Accept object from sender, but drop it afterward.

reject Return permanent error to sender.


Sorry my poor english, i hope this can help anybody using or trying this product under linux.

NOTE : this procedure is GPLed. Just keep my name on it.

Feel free to cantact me.
