How to Install Spamassasin, ClamAV, Amavis on Ubuntu \/ Debian Squeeze<\/h1>\n<\/header>\n
\n

 <\/p>\n

The purpose of this installation is to filter spam email and virus<\/strong> on Postfix<\/strong> mail agent. Here I already installed Postfix in the server, because it is included in EHCP installation<\/a>.<\/p>\n

1. Install the packages<\/p>\n

\n
\n\n\n\n
\n
1<\/div>\n<\/td>\n
\n
\n
$ sudo apt-get install amavisd-new spamassassin clamav-daemon<\/code><\/div>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n

2. Install the optional packages for better spam detection<\/strong><\/p>\n

\n
\n\n\n\n
\n
1<\/div>\n<\/td>\n
\n
\n
$ sudo apt-get install libnet-dns-perl libmail-spf-perl pyzor razor<\/code><\/div>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n

libmail-spf-query-perl<\/strong> package is not available in Debian<\/strong>, therefore I change to libmail-spf-perl<\/strong>.<\/p>\n

3. Install these optional packages to enable better scanning of attached archive files<\/p>\n

\n
\n\n\n\n
\n
1<\/div>\n<\/td>\n
\n
\n
$ sudo apt-get install arj bzip2 cabextract cpio file gzip lha nomarch pax rar unrar unzip zip<\/code><\/div>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n

I remove zoo<\/strong> and unzoo<\/strong> from the command line packages because Debian<\/strong> can\u2019t find the source.<\/p>\n

4. ClamAV<\/strong> configuration<\/p>\n

Add clamav<\/strong> user to the amavis<\/strong> group and vice versa in order for ClamAv to have access to scan files.<\/p>\n

\n
\n\n\n\n
\n
1<\/div>\n
2<\/div>\n<\/td>\n
\n
\n
$ sudo adduser clamav amavis<\/code><\/div>\n
$ sudo adduser amavis clamav<\/code><\/div>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n

5. Spamassassin<\/strong> configuration<\/p>\n

Edit \/etc\/default\/spamassassin<\/strong> to activate the Spamassassin<\/strong> daemon.<\/p>\n

\n
\n\n\n\n
\n
1<\/div>\n<\/td>\n
\n
\n
$ sudo nano \/etc\/default\/spamassassin<\/code><\/div>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n

Find the lines ENABLED=0<\/strong> and CRON=0<\/strong>, and update to the following:<\/p>\n

\n
\n\n\n\n
\n
1<\/div>\n
2<\/div>\n<\/td>\n
\n
\n
ENABLED=1<\/code><\/div>\n
CRON=1<\/code><\/div>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n

Start spamassassin:<\/p>\n

\n
\n\n\n\n
\n
1<\/div>\n<\/td>\n
\n
\n
$ sudo \/etc\/init.d\/spamassassin start<\/code><\/div>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n

6. Amavis<\/strong> configuration<\/p>\n

Activate spam and antivirus detection in Amavis by editing \/etc\/amavis\/conf.d\/15-content_filter_mode.<\/strong><\/p>\n

\n
\n\n\n\n
\n
1<\/div>\n<\/td>\n
\n
\n
$ sudo nano \/etc\/amavis\/conf.d\/15-content_filter_mode<\/code><\/div>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n

Uncomment the following lines:<\/p>\n

\n
\n\n\n\n
\n
1<\/div>\n
2<\/div>\n
3<\/div>\n
4<\/div>\n
5<\/div>\n<\/td>\n
\n
\n
@bypass_virus_checks_maps = (<\/code><\/div>\n
\\%bypass_virus_checks, \\@bypass_virus_checks_acl, \\$bypass_virus_checks_re);<\/code><\/div>\n
<\/div>\n
@bypass_spam_checks_maps = (<\/code><\/div>\n
\\%bypass_spam_checks, \\@bypass_spam_checks_acl, \\$bypass_spam_checks_re);<\/code><\/div>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n

Restart Amavis:<\/p>\n

\n
\n\n\n\n
\n
1<\/div>\n<\/td>\n
\n
\n
$ sudo \/etc\/init.d\/amavis restart<\/code><\/div>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n

7. Postfix<\/strong> integration<\/p>\n

Edit configuration file \/etc\/postfix\/main.cf<\/strong>:<\/p>\n

\n
\n\n\n\n
\n
1<\/div>\n<\/td>\n
\n
\n
$ sudo nano \/etc\/postfix\/main.cf<\/code><\/div>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n

Add this line into the file:<\/p>\n

\n
\n\n\n\n
\n
1<\/div>\n<\/td>\n
\n
\n
content_filter = amavis:[127.0.0.1]:10024<\/code><\/div>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n

Edit\u00a0<\/tt> \/etc\/postfix\/master.cf<\/strong><\/p>\n

\n
\n\n\n\n
\n
1<\/div>\n<\/td>\n
\n
\n
$ sudo nano \/etc\/postfix\/master.cf<\/code><\/div>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n

and add the following lines to the end of the file: (add 3 blank spaces in front of \u2018-0\u2019)<\/p>\n
