Amavisd updating

So remove comment "#" character and change socket path into /tmp/clamd on the lines below in

These lines starts with #cd /usr/local/src #groupadd clamav #useradd -g clamav -s /bin/false -c "Clam Antivirus" clamav #tar -zxf clamav-0.88.2gz #cd clamav-0.88.2 #./configure --sysconfdir=/etc #make #make install #mkdir /var/lib/clamav #chown clamav:clamav /var/lib/clamav Clamav is installedl Lets make a test to see how clamav is working.

We are doing our test under /usr/local/clamav-88.2 directory which contains sample virus-like files. #/usr/local/bin/clamscan -r -l /usr/local/clamav-0.88.2 Edit /etc/and modify variables like below; #Example Log File /tmp/Database Directory /var/lib/clamav User amavis UPDATING CLAMAV VIRUS DATABASE Every second a new virus/worm is created, we must update our virus database. Before running freshclam edit file and modify the line "Example" like below.

(Put # in front of it) #Example No create necessary log file and run freshclam; #touch /var/log/#chmod 600 /var/log/#chown amavis /var/log/#/usr/local/bin/freshclam --datadir=/var/lib/clamav -l /var/log/CLAMAV IN CRONTAB Create a crontab entry so that clamav will update its database everyday at regularly.

(in reply to end of DATA command))Hi Zhang,thank you.

Note Because of this setup, it is quite easily possible, to have these 3 mail 'handlers' on 3 different hosts.It could be possible to have the primary mailserver, that listens on port 25 on the firewall, have it forward to a safe isolated server running only amavis and have amavis sent mail to an internal postfix server where it delivers mail to the mail storage.perl -MCPAN -e shell install Archive:: Tar install Archive:: Zip install Compress:: Zlib install Convert:: UUlib install MIME:: Base64 install Mail:: Internet install Net:: Server install Net:: SMTP install Digest:: MD5 install IO:: Stringy install Time:: Hi Res install Unix:: Syslog install Berkeley DB install MIME:: Tools install Convert:: TNEF b) Create user account and home directory of amavis #mkdir /var/amavis #groupadd amavis #useradd amavis -g amavis -d /var/amavis -s /bin/bash #chmod 750 /var/amavis #mkdir /var/amavis/tmp #mkdir /var/amavis/db #chown -R amavis:amavis /var/amavis c) Install amavisd-new #cd /usr/local/src #tar -zxf amavisd-new-2.4.0gz #cd amavisd-new-2.4.0 #cp amavisd /usr/local/sbin #chown root /usr/local/sbin/amavisd #chmod 755 /usr/local/sbin/amavisd #cp /etc #chown root /etc/#chmod 644 /etc/#mkdir /var/virusmails #chmod 750 /var/virusmails/ #chown amavis /var/virusmails/ d) Edit /etc/file and adjust variables as below (If you haven't used the above scheme for directory structure, you will also need to change more variables than below) $mydomain = ''; $daemon_user = 'amavis'; $daemon_group = 'amavis'; $final_virus_destiny = D_REJECT; $final_banned_destiny = D_PASS; $final_spam_destiny = D_PASS; $final_bad_header_destiny = D_PASS; $warnvirussender = 1; $virus_admin = "genco\@$mydomain"; $mailfrom_notify_admin = "genco\@$mydomain"; $mailfrom_notify_recip = "genco\@$mydomain"; $mailfrom_notify_spamadmin = "NOSPAMMER\@$mydomain"; $sa_tag2_level_deflt = 5; e) You can set many virus scanners in file but we are going to use only clamav.If you create a file, it will be loaded after is loaded.This is the supported method for doing customizations of Spam Assassin for ZCS 8.
