Installing OpenWebMail in Slackware64 14.0

This article explains how to install OpenWebmail and configure it so that you can access your mailbox using a web interface from any place with internet access and a webbrowser available.
These instructions were tested on Slackware64 14.0 64-bit OS and the latest openwebmail-current.tar.gz (actually version 2.53)
It means, you are configured and running Apache web server and Sendmail mailserver.

Install libraries and required packages

Using CPAN via CPAN.pm:

perl -MCPAN -e shell                    [as root]
o conf prerequisites_policy ask

then:

install CGI
install Compress:Zlib
install Convert::ASN1
install Digest
install Digest::MD5
install IO::Socket::SSL
install MIME::Base64
install Net::SSLeay
install Text::Iconv

quit

Install OpenWebMail

First, download latest openwebmail: openwebmail-current.tar.gz
Create a directory wherever you want it, say “/ADISKS/openwebm_inst” and move the downloaded file “openwebmail-current.tar.gz” into that directory.
Extract all files using the command
```
tar -zxvBpf openwebmail-current.tar.gz
```
Use “tar” with “-zxvBpf” option, due to strange file permissions inside that archive. I tried to untar it via midnight comander built-in archive tools, ans the wrapsuid script would not work because of this…
Move the extracted directory “cgi-bin/openwebmail” to “/var/www/cgi-bin/openwebmail”
Move the extracted directory “data/openwebmail” to your webserver's DocumentRoot (in a default Apache configuration, that will be “/var/www/openwebmail”)
Change directory to “/var/www/openwebmail”, delete the file index.html and run the command
```
ln -s redirect.html index.html
```

Change directory to “/var/www/cgi-bin/openwebmail” and run the command

perl misc/tools/wrapsuid/wrapsuid.pl /var/www/cgi-bin/openwebmail

You should see the following output:

Then go to “/var/www/cgi-bin/openwebmail/etc” and edit the configuration files:

Change “openwebmail.conf” according to:

domainnames             auto                                                                                                                                
auth_module             auth_unix.pl                                                                                                                        
mailspooldir            /var/spool/mail                                                                                                                     
ow_cgidir               /var/www/cgi-bin/openwebmail                                                                                                        
ow_cgiurl               /cgi-bin/openwebmail                                                                                                                
ow_htmldir              /var/www/openwebmail                                                                                                                
ow_htmlurl              /                                                                                                                                   
logfile                 /var/log/openwebmail.log

Change directory to “/var/www/cgi-bin/openwebmail/etc/defaults”, edit auth_unix conf to become

passwdfile_plaintext    /etc/passwd                                                                                                                         
passwdfile_encrypted    /etc/shadow                                                                                                                         
passwdmkdb              none

In directory “/var/www/cgi-bin/openwebmail/etc/defaults”, edit db.conf as follows:

dbm_ext                 .db                                                                                                                                 
dbmopen_ext             .db                                                                                                                                 
dbmopen_haslock         no

Then, change directory to “/var/www/cgi-bin/openwebmail” and run
```
./openwebmail-tool.pl --init
```

After that, go to “/var/www/cgi-bin/openwebmail”, check that there are files starting with a dot (like “.openwebmail.pl”) and old-style filenames (like “openwebmail.pl)”. Set the suid bit for these scripts:
```
chmod u+s openwebmail*.pl
chmod u+s .openwebmail*.pl
```

Apache additional configuration

Add a AddHandler cgi-script .cgi .pl option in /etc/httpd/httpd.conf in section “Directory /srv/httpd/” httpd.conf like be:

ServerRoot "/usr"
