Question

Sendmail and AMAVIS Configuration

Asked by: ashok_cse

Hi,
I am using Linux sendmail-8.11.6-15 server.
I heard about AMAVIS very recently and have been trying to configure it with my mail server.
I am not clear with what are all the packages I should install and also with what should I do with my sendmail.mc file.
Presently I installed both amavis-perl-11 and amavisd-snapshot.
Which one is required?or do we need both?
And..
Do I need to create group named amavis and user named vscan and amavis?
In the installation document, it is mentioned that we need replace Mlocal procmail with scanmails. As of now I dont have any executable file called scanmails after installing amavis package.
Could you please tell me how should I configure AMAVIS with my version of sendmail?

Expecting reply at the earliest.

Thanks

hello Ashok,

Let me give you step by step instruction in installing Amavis and a Clamv Antivirus scanner they both work together and scan your incoming/outgoing email for viruses.

First grab a copy of Clamav Antivirus from

http://clamav.elektrapro.com/stable/clamav-0.54.tar.gz

then ssh to your server and su .

extract clamav-0.54.tar.gz

then cd to ur clamav-0.54

[root@ns1 /]# groupadd clamav
[root@ns1 /]# useradd -g clamav -s /bin/false -c "Clam AntiVirus" clamav

[root@ns1 /]# ./configure
[root@ns1 /]# make
[root@ns1 /]# make install

once it got done it will install the files in your /usr/local/bin

cd  to your /usr/local/bin then do

./freshclam

it will update the virus defination.

then on your promit do ./clamd it will tell u the location of your clamav.conf file it will generally save in

/usr/local/etc/clamav.conf

then pico /usr/local/etc/clamav.conf

and then in line number eight

# Comment or remove the line below.
#Example

save and exit.

Now you are done installing the Clam AntiVirus scanner.

Now the next step is to install amavis , I may suggest you to install amavis-perl version

grab a copy from
http://www.amavis.org/dist/perl/amavis-perl-11.tar.gz

once you got done extracting that above software. First install the following modules.

perl -MCPAN -e shell

  install Unix::Syslog
  install Convert::UUlib
  install Convert::TNEF
  install Compress::Zlib
  install Archive::Tar
  install Archive::Zip
  install G/GB/GBARR/MailTools-1.15.tar.gz
  install MIME::Tools
  install Bundle::libnet

once you install all the above perl modules then make sure you have the following software installed in your server.

 o arc
 o bunzip2 (part of the bzip2 package)
 o lha
 o unarj
 o uncompress (standard on Unix and Unix-like systems)
 o unrar
 o zoo

you can get those above software from

http://www.rpmfind.net

install those software by using

rpm -Uvh software.rpm


once you are done installing the above Rpms then cd to your clamav-0.54/support/amavis

look for clamavis.patch

cp clamavis.patch /home/viruses/amavis-perl-11/

patch -p1 < clamavis.patch
find . -exec touch 01010000 {} \;

no ./configure
make;make install

now you are done installing amavis-perl .

I may suggest you editing your sendmail.cf manually by but before editing make sure to make a backup of your sendmail.cf

pico sendmail.cf

look for Mlocal

remove the previous Mlocal like and insert

Mlocal,         P=/usr/sbin/amavis, F=lsDFMAw5:/|@qSPfhn9, S=EnvFromL/HdrFromL, R=EnvToL/HdrToL,
                T=DNS/RFC822/X-Unix,
                A=amavis $f $u /usr/bin/procmail -t -Y -a $h -d $u

once you are done restart your sendmail and you are DONE .


send your self a test message once you got an email check the message source and it will say Amavis Virus Scanner.

Take kAre,

Sohaib (K)

Subject:      *_*_destiny setttings do not work when sql_select_policy

For some reason whenever I configure amavis.conf to work with a sql database for policy it does not work in conjunction with the *_destiny settings.  I would like to D_REJECT all mail that is considered spam but store it in quarantine. Here is a snippit of the config:

----------------------amavis.conf--------------------------

#*_destiny config
$final_virus_destiny      = D_REJECT;  # (defaults to D_BOUNCE)
$final_banned_destiny     = D_REJECT;  # (defaults to D_BOUNCE)
$final_spam_destiny       = D_REJECT;  # (defaults to D_REJECT)
$final_bad_header_destiny = D_REJECT;  # (defaults to D_PASS), D_BOUNCE suggested
#SQL Config
@lookup_sql_dsn =( ['DBI:mysql:database=amavis;host=localhost', '****', '*****'] );
$sql_select_policy = 'SELECT *,users.id FROM users,policy'.
     ' WHERE (users.policy_id=policy.id) AND (users.email IN (%k))'.
     ' ORDER BY users.priority DESC';
#$sql_select_policy = undef;
$sql_select_white_black_list = 'SELECT wb FROM wblist'.
  ' WHERE (rid=?) AND (wblist.email IN (%k))'.
  ' ORDER BY wblist.priority DESC'; # undef disables SQL white/blacklisting


The *_destiny works when I declare $sql_select_policy = undef but then the black/white list query does not.  The *_destiny settings also works when I disable lookup_sql_dsn.  When enabled it looks like all of the queries work as configured.  


I installed the following packages on top of squirrelmail 1.4.3

amavis-new rpm package - 20030616-9
amavisnewsql-0.7.2-1.4
