I have successfully install sendmail with clamav-milter. And it’s running fine. Here I write step by step installation documentation so that anyone can easily install sendmail with clamav-milter at most of Linux distribution.
My installation platform is:
-Sendmail-8.12
-ClamAV-75
STEP NO.1:
Check that MILTER support is enable at Sendmail. To check it, run the following command:
#sendmail -d0 < /dev/null | grep MILTER
If MILTER support is already enable, this will show the following like message,
DNSMAP LOG MAP_REGEX MATCHGECOS MILTER MIME7TO8 MIME8TO7
Most of the case you will see that MILTER is enable by default. If MILTER is not enable, then you need to rebuild your sendmail with MILTER support from its binary source.
STEP NO.2:
Check that MILTER library "libmilter*" is installed.
#whereis libmilter
This will show “libmilter” files. If “libmilter” is not installed it can't find any “libmilter” files. In most cases "libmilter" is not installed by default. So, you need to install it. To install “libmilter” you need to download sendmail binary source software from www.sendmail.org depending on your sendmail version. If you are using sendmail-8.12 then you need to download sendmail-8.12 version binary source from www.sendmail.org .
#cd /usr/local/src
#tar zxvf /usr/local/download/sendmail-8.12.11.tar.gz
#cd sendmail-8.12.11
#cd libmilter
#sh Build install
Now run,
#whereis libmilter
This will locate all "libmilter" related files. At this moment your sendmail is realy to work with Clamav-milter.
STEP NO.3:
Download latest stable clamav source from www.clamav.net .
#cd /usr/local/src
#tar zxvf clamav-0.75.tar.gz
#cd clamav-0.75
#./configure --enable-milter
And check that /usr/local/sbin/clamav-milter is exists.
STEP NO.4:
Read the clamav configuration file /usr/local/etc/clamav.conf and edit it to suit your requirements.
Even you can edit (just uncomment the #) it as:
LogFile /var/log/clamav/clamd.log
LogFileUnlock
LogClean
LogVerbose
LocalSocket /var/run/clmilter.sock
FixStaleSocket
StreamSaveToDisk
StreamMaxLength 10M
ScanMail
ScanArchive
ScanRAR
ArchiveMaxFileSize 10M
Then create clamav log file and directory,
#mkdir /var/log/clamav
#touch /var/log/clamav/clamd.log
#chown -R clamav.clamav /var/log/clamav
Then run clamd and clamav-milter,
#/usr/local/sbin/clamd
#sudo /usr/local/sbin/clamav-milter --max-children=2 -olb \
local:/var/run/clamav-milter.sock
Check that clamd and clamav-milter process is running and its log file.
#ps ax | grep clamd
#tail -f /var/log/clamav/clamd.log
STEP NO.5:
Read and configure the clamav auto updating program freshclam configuration file /usr/local/etc/freshclam.conf.
You can edit it as:
UpdateLogFile /var/log/clamav/freshclam.log
LogVerbose
DatabaseMirror database.clamav.net
MaxAttempts 3
Checks 12
Checks 8
NotifyClamd
Then create freshclam log file and directory
#touch /var/log/clamav/freshclam.log
#chown -R clamav.clamav /var/log/clamav
Now run freshclam as a daemon,
#/usr/local/bin/freshclam -d
And check log,
#tail -f /var/log/clamav/freshclam.log
STEP NO.6:
Now configure your sendmail to use clamav-milter.sock socket. To do this, edit your sendmail.mc file, rebuild your sendmail.cf file and finally retsart your sendmail service and check log file.
Edit your sendmail.mc and add the following line,
INPUT_MAIL_FILTER(`clamav', `S=local:/var/run/clamav-milter.sock, F=T, T=S:4m;R:4m')
#m4 sendmail.mc > sendmail.cf
#/etc/init.d/sendmail restart
STEP NO.7:
We need to start our clamav and freshclam automatically with our Linux default runlevel, So we need to create a startup script for clamav and freshclam at /etc/init.d/
#cd /etc/init.d
#vi clamav.sh
Add the following lines at clamav.sh file:
#!/bin/bash
#for clamd and clamav-milter
/usr/local/sbin/clamd
sudo /usr/local/sbin/clamav-milter --max-children=2 -olb \
local:/var/run/clamav-milter.sock
#for freshclam as a daemon
/usr/local/bin/freshclam -d
Save it. Then make it executable,
#chmod u+x clamav.sh
Then run it and check the process,
#./clamav.sh
#ps ax | grep clam
And finally make a soft link with it at your default runlevel. My default runlevel is 3.
#cd /etc/rc.d/rc3.d
#ln -s /etc/init.d/clamav.sh S80clamav
Reboot and check process and log files so that your clamav, freshclam and sendmail are running properly.
