AVG Linux Email Server / User Manual

4. Third Party Products

Third party software is needed to preprocess incoming and outgoing e-mail

messages content before they can be scanned by

AVG for Linux E-mail Server.

Two solutions are available for particular e-mail servers – the

AMaViS and the

Qmail-Scanner security packages.

Both of these packages require

AVG for Linux E-mail Server and optionally some

AVG Anti-Virus vendor patches to be installed before attempting to install and

configure them properly on your system. The

AMaViS e-mail content scanner can

be used with the

sendmail, postfix, qmail and exim mail transport agents; the

Qmail-Scanner can be used with qmail only.

Supported commercial e-mail servers (

Lotus Notes/Domino and Kerio

MailServer

) do not require such tools. See chapter 6. Commercial E-mail Servers

for more information on this topic.

4.1. AVG Anti-Virus Vendor Patches

Before installing the

AMaViS package amavis (various versions supported) you

must apply the

AVG Anti-Virus patch. Supposing you have unpacked the

installation file, switch to the unpacked directory, copy the

amavis-{version}-

avg.patch

file there (included in the AVG for Linux

E-mail Server installation package), and apply the patch using the

$ patch -p1 < amavis-{version}-avg.patch

command.

Run

autoconf with the

$ autoconf

command.

Then create the

aclocal.m4 file using the

$ touch aclocal.m4

command and continue with the installation as described in chapter

4.2 Third Party

Products/AMaViS.

Note: The patch is needed only for the amavis variant of AMaViS. For the version

‘p7’ and higher of the recommended

amavisd-new you just have to uncomment

the

AVG Anti-Virus related lines in the amavisd.conf file. For older versions, use

the respective

amavisd-new patch

Besides the

amavis patch, the Qmail-Scanner (versions 1.20, 1.22) patch is also

needed when you are planning to install this tool. Switch to the unpacked

Qmail-

Scanner

installation directory and copy the qmail-scanner-{version}-avg.patch

file (included in the

AVG for Linux E-mail Server installation package) there.

Apply the patch using the
