How to set up Open WebMail in CentOS
# cd /etc/yum.repos.d
# wget http://openwebmail.org/openwebmail/download/redhat/rpm/release/openwebmail.repo
Now, Open WebMail can be easily set up using yum command.
# yum install openwebmail perl-CGI httpd
Configuring Open WebMail
First of all, the file /var/www/cgi-bin/openwebmail/etc/dbm.conf is updated with the following parameters.
# vim /var/www/cgi-bin/openwebmail/etc/dbm.conf
## the previous values are overwritten ##
dbm_ext .pag
dbmopen_ext none
dbmopen_haslock no
Then Open WebMail can be initialized with an installed script as follows.
# /var/www/cgi-bin/openwebmail/openwebmail-tool.pl --init
The index.html file for Open WebMail is also prepared by using a soft link.
# ln -s /var/www/data/openwebmail/redirect.html /var/www/html/index.html
[Optional] The domain name for the mail server is defined manually to avoid any future mistakes in the @domain part
of the mail address.
# vim /var/www/cgi-bin/openwebmail/etc/openwebmail.conf
domainnames example.tst
The Apache web server is restarted.
# service httpd restart
# chkconfig httpd on
Finally, Open WebMail can be accessed by pointing the browser to the URL of the mail server: http://mail.example.tst
OR http://IP-Address-of-Mail-Server

Open WebMail in CentOS Open WebMail login page: Open WebMail interface: Open WebMail preferences: Troubleshooting Open WebMail Open WebMail may generate errors or behave abnormally if specific versions of some Perl packages are not installed. Fortunately, the packages are available in Open WebMail repository and are very easy to install. The following demonstrates how to install problematic Perl packages.
- 3. Open WebMail in CentOS A folder is created to store the packages. It could be any folder. # mkdir /var/www/data/openwebmail/packages # cd /var/www/data/openwebmail/packages Packages are downloaded. # wget http://openwebmail.org/openwebmail/download/packages/CGI.pm-3.05.tar.gz # wget http://openwebmail.org/openwebmail/download/packages/MIME-Base64-3.01.tar.gz # wget http://openwebmail.org/openwebmail/download/packages/Text-Iconv-1.2.tar.gz Install CGI. # tar zxvf CGI.pm-3.05.tar.gz # cd CGI.pm-3.05 # perl Makefile.PL; make; make install Install MIME. # tar zxvf MIME-Base64-3.01.tar.gz # cd MIME-Base64-3.01 # perl Makefile.PL; make; make install Install Text-Iconv. # tar zxvf Text-Iconv-1.2.tar.gz # cd Text-Iconv-1.2 # perl Makefile.PL; make; make install To sum up, Open WebMail interface may be a bit old school, but it is a complete package pre-built with often needed features. Besides, the installation process is easy, and the interface is very lightweight. Open WebMail is certainly a worthy candidate when a simple webmail interface is needed.
