Avira GmbH Avira AntiVir MailGate 46
5.4 Scanner Configuration in avmailgate-scanner.conf
A new configuration file has been introduced, starting with MailGate v 3.0.0:
avmailgate-scanner.conf. It contains configuration options specific to the new
scanner backend. Usually, you don't have to change the options in this file, but
there might be a few exceptions.
User,
Group
If you change one of these options, you have to make sure that the files
avmailgate-scanner.conf and avmailgate.conf contain the same values for these
options.
You also have to adapt avmailgate-scanner.conf if you updated from a previous
MailGate version (< 3.0.0) and the current settings for User/Group differ from
the default settings. Defaults:
User uucp
Group antivir
There are some other changes needed when changing User/Group:
In /etc/avmailgate-scanner.conf:
• Change the owner/group of the path given with ListenAddress (The
option consists of a path and a socket file. Don't forget to stop MailGate
before making any changes. If the socket file exists, delete it and only change
the owner/group of the directory.)
In /etc/avmailgate.conf:
• Change the option User/Group
• Change the owner/group of the directory and its sub directories given with
SpoolDir (default: /var/spool/avmailgate).
Socket
Permissions
The owner and permissions of the scanner backend's socket. The scanner backend
must run as the same user as MailGate runs.
SocketPermissions 0600
ListenAddress
ListenAddress (in avmailgate-scanner.conf) and ScannerListenAddress (in
avmailgate.conf) specify how the scanner backend can be reached. Both options
must point to the same path (the string "unix:" must not be used with the option
ScannerListenAddress):
ListenAddress unix:/var/run/avmailgate/scanner
In /etc/avmailgate.conf:
ScannerListenAddress /var/run/avmailgate/scanner
UseSavapi
Proxy
To make scanning processes more efficient, you can use a given pool of scanners.
Please note that too many scanners would overload the computer, while too few
would cause unnecessary waiting for applications. Values: 0 or 1. Default:
When changing the user and/or group here, you must also change the options User and
Group in MailGate's configuration file (/etc/avmailgate.conf).
