AVG Linux Email Server / User Manual

$ patch -p1 < qmail-scanner-{version}-avg.patch

command, and follow the installation instructions as described in chapter

4.3 Third

Party Products/Qmail-Scanner.

4.2. AMaViS

You can download the package from the

http://www.amavis.org/download/ page.

Four separate packages are available:

z amavis for low and medium mail volume (home or small office use with up to

ten accounts)

z amavisd for higher mail volume

z amavisd-new for higher mail volume with various add-ons included (such as

anti-spam or ISP features)

Note: We strongly recommend the amavisd-new variant to be used with

AVG for Linux E-mail Server!

z amavis-ng, a modular rewrite of amavis (intended for experienced

administrators and/or

AMaViS developers); this project is not being

developed any longer, although its source code can be obtained via the

AMaViS CVS repository.

Prerequisites

The C language compiler and also the

make and autconf / automake

utilities are needed to build the AMaViS tools.

The essential modules responsible for extracting e-mail content and passing it

to the

AVG for Linux E-mail Server scanning engine are implemented in

Perl. This is why the Perl language interpreter has to be installed on your

system. The following Perl modules are required:

o Archive::Tar (Archive-Tar-x.xx)

o Archive::Zip (Archive-Zip-x.xx, version 1.09 or later is recommended!)

o Compress::Zlib (Compress-Zlib-x.xx)

o Convert::TNEF (Convert-TNEF-x.xx)

o Convert::UUlib (Convert-UUlib-x.xxx, stick to the newest version)

o MIME::Base64 (MIME-Base64-x.xx)

o MIME::Parser (MIME-Tools-x.xxxx)

o Mail::Internet (MailTools-1.58 or later have workarounds for Perl 5.8.0

bugs)

o Net::Server (Net-Server-x.xx)

o Net::SMTP (libnet-x.xx, use libnet-1.16 or later for better

performance)

o Digest::MD5 (Digest-MD5-x.xx)

o IO::Stringy (IO-stringy-x.xxx)
