heuuu ça veut dire quoi ca ?
Mon expérience LaTeX à travers des exemples, des solutions mais aussi quelques mises en reliefs de packages LaTeX.
C'est sur la 1ere page.

Sinon pour ceux que ca branche, et puisqu'on parle de postfix, j'ai baclé une doc en innegliche sur l'installation d'Amavis avec Postfix (testé sur une MDK). C'est un peu crado mais la doc "officielle" est assez incomplète. A toutes fins utiles...


Installing Amavis with Postfix on Mandrake Linux, using Sophos.
V 0.01 20010904 - 12:22

1 - Install Antivirus
1.1 Install Sophos from http://www.sophos.com(...) (need Login + passwd, see
http://www.sophos.com/downloads/products/(...) ).
# ./install.sh -ni

1.2 Install Sophos updates (.ide files) in /usr/local/sav

2 - Install Amavis
2.1 Required software

These are software *not* provided with Mandrake Linux (2 CDs set)

cf http://www.amavis.org/amavis.html(...)

arc ftp://rpmfind.net/linux/contrib/libc6/i386/arc-5.21e-4.i386.rpm(...)

unrar ftp://rpmfind.net/linux/Mandrake-devel/contrib/RPMS/unrar-2.50-1md(...)

Perl modules (perl -MCPAN -e shell). You'll need perl-devel and Lynx.
Unix/Syslog Unix::Syslog
Convert/UUlib Convert::UUlib
Convert/TNEF Convert::TNEF
Archive/Tar Archive::Tar
Archive/Zip Archive::Zip

2.2 Install Amavis

Modify the files "admin", "recip" and "sender" in /<your source dir>/amavisd-<version>/amavis/notify/ if you wish to change the
default warning message.

# adduser vscan
# rm -rf /home/vscan

Edit /etc/passwd to remove home directory for vscan
*LEAVE* a valid shell (/bin/bash is good, rbash does not work) !
Edit /etc/shadow to change the password for vscan to prevent direct login ("*" is a good one).
Check that somebody gets vscan's mail (/etc/aliases). While you're there, check that somebody gets virusalert's and postmaster's mail.

# killall amavisd
# make clean && make distclean
# ./configure --enable-postfix --with-sophos-ide=/usr/local/sav --enable-syslog --with-amavisuser=vscan --enable-smtp --with-smtp-port=10025 --with-warnsender --with-warnrecip --with-warnadmin
# make && make install
# service postfix stop
# su vscan -c /usr/sbin/amavisd
# service postfix start
# su vscan -c 'make check'

Add
content_filter = vscan:
to /etc/postfix/main.cf

Add
vscan unix - n n - 10 pipe user=vscan argv=/usr/sbin/amavis ${sender} ${recipient}
localhost:10025 inet n - n - - smtpd -o content_filter=
to /etc/postfix/master.cf.

# service postfix restart

3 - Test

$ echo "X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*" > /tmp/eicar.com
Send a mail with the file /tmp/eicar.com. It should be detected as a virus and get bounced back to the sender and the admin with a
warning message.
You can also try with a "real" virus. Back Orifice is available here : http://www.mut3x.com/cdc/bo120.zip.(...) It should be detected even
when zipped.

4 - Tuning

4.1 Automatically update antivirus files

Try this in some crontab file

---------------------------------< cut here
#!/bin/bash

#cd $SAV_IDE
cd /usr/local/lib/sweep-IDE

/usr/bin/wget -q -N `/usr/local/bin/sweep -v |/usr/bin/grep "Product version"
|/usr/bin/sed -e "s/.*: \(.\)\.\(..\)$/
http:\/\/www.sophos.com\/downloads\/ide\/1円2円_ides.zip/"`
/usr/bin/unzip -q -n "???_ides.zip"

chmod 644 *
---------------------------------< cut here

4.2 Start amavisd on startup

Start it *before* postfix.
Put this in /etc/init.d/amavisd :
------------------------------------------------------< cut here
#!/bin/sh
#
# amavisd This shell script takes care of starting and stopping
# the amavis daemon (mail antivirus).
#
# chkconfig: 2345 60 40
#
# description: Amavisd is the daemon that interracts with the antivirus to
# check mails for wiruses
#

# Source function library.
. /etc/rc.d/init.d/functions

# Source networking configuration.
. /etc/sysconfig/network

# Check that networking is up.
[ ${NETWORKING} = "no" ] && exit 0

[ -f /usr/sbin/amavisd ] || exit 0

# See how we were called.
case "1ドル" in
start)
# Start daemons.
echo -n "Starting amavisd: "
/bin/su vscan -c /usr/sbin/amavisd
touch /var/lock/subsys/amavisd
;;
stop)
# Stop daemons.
echo -n "Shutting down amavisd: "
/usr/bin/killall amavisd 2>/dev/null
echo amavisd
rm -f /var/lock/subsys/amavisd
;;
restart)
0ドル stop
0ドル start
;;
*)
echo "Usage: 0ドル {start|stop|restart}"
exit 1

esac

exit 0
--------------------------------------------------------< cut here

#chkconfig amavisd --reset
