Were going to setup a e-mail server using postfix as our smtp server, dovecot as our pop3/imap server, ClamAV as out anit-virus and MailScanner as out e-mail anti-virus scanner on a fedora core 3 box & ilohamail as out webmail client.

Name: Dovecot
HomePage: http://dovecot.org/
Fuction: Dovecot is an open source IMAP and POP3 server for Linux/UNIX-like systems, written with security primarily in mind.

Name: Clamav
HomePage: http://www.clamav.net
Fuction: An open source anti-virus

Name: Postfix
HomePage: http://www.postfix.org/
Fuction:  Postfix attempts to be fast, easy to administer, and secure, while at the same time being sendmail compatible enough to not upset existing users

Name: MailScanner
HomePage: http://www.mailscanner.info/
Fuction: Scans all incomming and outgoing e-mails useing the system's anti-virus.

Name: Ilohamail
Homepage: http://blog.ilohamail.org/
fuction: Webmail client, used to check e-mails from anywhere in world, via the internet, like gmail or hotmail

1. Edit the /etc/dovecot.conf file to include the following line (if you want all services running then include them all, if only one then include only the one running that you want)

nano /etc/dovecot.conf

2. start/restart the dovecot server by the command

/etc/init.d/dovecot start

3. Now download the latest version from, http://blog.ilohamail.org/ then make the folder /usr/lib/ilohamail/ and unzip the downloaded file into the folder you just created.

4. Once you have unpacked it, then place a link in the root directory of the apache web server.

ln -s /usr/lib/ilohamail/IlohaMail/source/ /var/www/html/ilohamail

5. Now change the ownership of the folder so people surfing the web can access it.

chown apache:apache -R /usr/lib/ilohamail/IlohaMail/source/
chmod -R u+rwx /usr/lib/ilohamail/IlohaMail/source/

6. Make sure that apache is running

/etc/init.d/httpd start

7. Then go to http://ip-address-of-your-machine/ilohamail/

8. Once at this site you may notice there is an option of language, service (imap/pop3) and server, if you don't want your clients to be able to change or see these options then edit the file

nano /usr/lib/ilohamail/IlohaMail/conf/login.php

the file it's self should have plenty of instructions on what to do.

9. Next we need to install the anti virus software, the rpm's can be downloaded from

http://crash.fce.vutbr.cz/crash-hat/3/clamav/

or the source can be downloaded from

http://www.clamav.net

10. Then we install it and start the Clam AV daemon

rpm -ivh clamav-db-0.88.2-1.i386.rpm
rpm -ivh clamav-devel-0.88.2-1.i386.rpm
rpm -ivh clamav-server-0.88.2-1.i386.rpm
rpm -ivh clamav-0.88.2-1.i386.rpm

/etc/init.d/clamd start

11. Once the anti-virus is install then we need to install the MailScanner software the RPM along with the source files can be found at

http://www.sng.ecs.soton.ac.uk/mailscanner/downloads.shtml

12. Now get ready to install the mailscanner, this is going to take a long time.

gzip -d MailScanner-4.46.2-2.rpm.tar.gz
tar -xvf MailScanner-4.46.2-2.rpm.tar
cd MailScanner-4.46.2-2
./install.sh

13. In your MailScanner.conf file in /etc/MailScanner, there are 5 settings you need to change. The settings are:

nano /etc/MailScanner/MailScanner.conf

14. You will need to ensure that the user "postfix" can write to

/var/spool/MailScanner/incoming and /var/spool/MailScanner/quarantine

chown postfix:postfix /var/spool/MailScanner/incoming
chown postfix:postfix /var/spool/MailScanner/quarantine

15. Edit file MailScanner.conf

nano /etc/MailScanner/MailScanner.conf

16. Now we need to edit the postfix main.cf file, go all the way to the bottom of the file and add the following

nano /etc/postfix/main.cf

17. In the file /etc/postfix/header_checks add this line:

18. Now change the MTA alternatives --config mta

19. Now for the management of these programs, webmin is a great tool and all of these programs have webmin modules.

ClamAV Webmin Module: http://wbmclamav.labs.libre-entreprise.org/

MailScanner:  http://sourceforge.net/projects/msfrontend/

20. Webmin configuration information:

Full path to MailScanner program:                         /usr/sbin/MailScanner
Full path and filename of MailScanner config file:     /etc/MailScanner/MailScanner.conf
Full path to the MailScanner bin directory:             /usr/sbin/
Full path and filename for the MailScanner pid file:  /var/run/MailScanner.pid
Command to start MailScanner:                           /etc/init.d/MailScanner start
Command to stop MailScanner:                           /etc/init.d/MailScanner stop

21. Set the servers to run on startup and then start them

chkconfig dovecot on
chkconfig MailScanner on
chkconfig postfix on
chkconfig clamd on

/etc/init.d/Mailscanner start
/etc/init.d/postfix start
/etc/init.d/dovecot start
/etc/init.d/clamd start
